        2p2h effects on the weak pion production cross section 1h 30m
        The one pion production process νA →A'lπN results to be an important background to the quasielactic νA →A'lN process used as signal in neutrino oscillation experiments, at the moment of constrain fake events. When only 1p1h final states are considered, the calculated cross section is rough 50% below the experimental data. In this contribution we analyze the effect of adding 2p2h final states.

        A-dependence of weak nuclear structure functions 1h 30m
        We shall present the results for the ratio of weak nuclear structure functions $\frac{F_{2}^{A}}{F_{2}^{proton}}$ and $\frac{F_{3}^{A}}{F_{3}^{proton}}$, where A is the different nuclear targets like $_1^2D$, CH, $H_{2}O$, $^{56}Fe$ and $^{208}Pb$ which are being used in the ongoing Miner$\nu$A experiment at Fermilab. We have studied these nuclear structure functions using relativistic nuclear spectral function which incorporate Fermi motion, nuclear binding, and nucleon correlations. We have also included the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. Shadowing and anti-shadowing effects have also been taken into account. The deuteron structure functions have been calculated using the same formulas as used for the weak nuclear structure functions, but performing the convolution with the deuteron wave function squared instead of the spectral function. For the numerical calculations, parton distribution functions for the nucleons have been taken from the parametrization of CTEQ Collaboration (CTEQ6.6) and we have performed the calculations at LO as well as at NLO. The details of the model are given in Refs. 1. $\nu(\bar\nu)$-208Pb deep inelastic scattering. H. Haider, I. Ruiz Simo and M. Sajjad Athar Phys. Rev. C 85 (2012) 055201. 2.

        CHARGED CURRENT INCLUSIVE ANALYSES IN MINERvA 1h 30m
        MINERvA is a few-GeV neutrino scattering experiment that has been taking data in the NuMI beam line at Fermilab since November 2009. The experiment will provide important inputs, both in support of neutrino oscillation searches and as a pure weak probe of the nuclear medium. For this, MINERvA employs a fine-grained detector, with an eight ton active target region composed of plastic scintillator and a suite of nuclear targets composed of helium, carbon, iron, lead and water placed upstream of the active region. In this poster, we present the current status of the charged current inclusive analysis in plastic scintillator as well as in the nuclear targets.

        Charged Current Neutral Pion Production at MINERvA 1h 30m
        MINERvA is a neutrino experiment located at Fermilab. The main goal of the experiment is to study neutrino interactions using different targets and to measure differential neutrino cross sections. In this poster we concentrate on Charged Current Neutral Pion Production at the MINERvA experiment where the signal is defined as a muon, nucleon and neutral pion in the final state. The reconstructed neutral pion invariant mass and a comparison between data and Monte Carlo is shown.

        CONNIE: Coherent Neutrino-Nucleus Interaction Experiment 1h 30m
        This is a new experiment intended to detect very low energy neutrinos coming from a nuclear reactor using CCDs (Charge Coupled Devices). These silicon detectors have very low energy threshold (~7eV RMS) and very good spatial resolution (~15um). Also, nowadays, it is possible to fabricate very thick CCDs (~250um) increasing the detecting mass to 1g. All these characteristics make them a perfect candidate for detecting low energy neutrinos by coherent elastic neutrino-nucleus scattering. The experiment is going to be running at Angra Nuclear Power Plant in Brazil since 2013.

        Determination of $sin^2\theta_W$ using $\nu(\bar\nu)$-Nucleus scattering 1h 30m
        We shall present the results of our study of non-isoscalarity corrections and nuclear medium effects in the extraction of $sin^2\theta_W$ using Paschos-Wolfenstein(PW) relation. PW relation for an isoscalar nuclear target is defined as \begin{eqnarray} \label{ratio_cross} R_{PW}=\frac{\sigma(\nu_\mu~A \rightarrow \nu_\mu~X)~-~\sigma(\bar\nu_\mu~A \rightarrow \bar\nu_\mu~X)}{\sigma(\nu_\mu~A \rightarrow \mu^-~X)~-~\sigma(\bar\nu_\mu~A \rightarrow \mu^+~X)}=\frac{1}{2}~-~\sin^2 \theta_W \end{eqnarray} where $\sigma(\nu_\mu(\bar\nu_\mu)~A \rightarrow \nu_\mu(\bar\nu_\mu)~X)$ is the neutral current induced neutrino(antineutrino) cross section, $\sigma(\nu_\mu(\bar\nu_\mu)~A \rightarrow \mu^-(\mu^+)~X)$ is the charged current induced neutrino(antineutrino) cross section for a Z=N nuclear target A, and $\theta_W$ is the Weinberg angle. The above relation is valid for the total as well as differential cross sections. The differential cross section is expressed in terms of nuclear structure functions. We have studied nuclear medium effects in the structure functions $F_{2}^{A}(x,Q^2)$ and $F_{3}^{A}(x,Q^2)$ by taking into account Fermi motion, nuclear binding, shadowing and antishadowing corrections and pion and rho meson cloud contribution. Calculations have been performed in a local density approximations using relativistic nuclear spectral functions which include nucleon correlation. These structure functions are calculated with target mass correction (TMC) and CTEQ6.6 parton distribution functions (PDFs) at the Leading-Order (LO).

        How much does MSW contributes to the reactor neutrino anomaly? 1h 30m
        Reactor neutrino experiments have observed a 5% deficit of electron anti-neutrino flux, when compared to the one predicted from nuclear physics as a product of the reactor's fission chains. One aspect that might have been overlooked in the literature is the contribution from extreme non-adiabatic effects coming from "decompression" when leaving the high density nuclear fuel rods. This work explores a analytic solution for this effect and presents its contribution to the reactor neutrino deficit.

        Measurement of neutrino induced NC-1\pi^0 using the ND280 Tracker region 1h 30m
        Single \pi^0 production is one of the most important backgrounds in the \nu_\mu->\nu_e appearance measurement in T2K. Large uncertainties in this production rate make it difficult to predict. Therefore, measurement at the near detector (ND280) is required to constrain efficiently not only the background prediction at the far detector (Super-K) but also at the near detector to improve knowledge of the intrinsic \nu_e contamination within the beam. We present an analysis based on Monte Carlo simulation of neutral current (NC) single \pi^0 production in the tracker region of ND280. NC-1\pi^0 are selected using a specific two-gamma signature in the tracker. The first gamma from the pi0 decay is reconstructed by selecting an e^+/e^- pair starting in the Fine-Grained target Detector (FGD) and extending into the TPC, where the leptons can be identified and their momentum measured accurately. The second gamma is then selected in time in the calorimeter modules surrounding the tracker. We will present in detail selections cuts, efficiency and purity of the selection. A projection of the expected number of single pi0 candidates that are expected for 3 x 10E20 POT exposure (run I+II+III data) will be given.

        Measurement of the muon background at the Angra Neutrino laboratory 1h 30m
        The Angra II nuclear reactor, which has the 4 GW of thermal power, is located in the Angra dos Reis nuclear power plant in the State of Rio de Janeiro in Brazil. The large fission rate of 10²⁰ per second produce about 5000 antineutrino interactions per day in a detector with only 1 m³ at the distance of 30 m from the reactor core. As the flux of antineutrinos is proportional to the thermal power delivered by the reactor, by measuring the interaction rate of antineutrinos in the detector, we expect to be able to monitor the thermal power generated by the reactor in quasi-real time as well as the time evolution of the composition of the nuclear fuel. However, in order to observe antineutrinos coming from the reactor, we have to veto muons, one of the most important background components. Moreover, energetic muons can produce neutrons through the process of spallation that can mimic the neutrons generated by the neutrino interaction, increasing the background. In this work we have performed the measurement of the muon flux at sea level as these data are very important to estimate the background level in the antineutrino detector.

        Measurements of pion production in eA with the CLAS detector 1h 30m
        Preliminary results on semi-inclusive charged pion production in eA collisions at Ebeam=5 GeV/c2 are presented. These data are thought to be useful for tuning the hadronic production models used in extracting results from current and next-generation neutrino oscillation experiments. The data were collected using the CLAS detector, which is a multipurpose, large acceptance, magnetic spectrometer located in Hall B at the Thomas Jefferson National Accelerator Facility. Distributions (integrated and differential) in W, Q2, pion momentum , and pion angle are shown for data produced using Deuterium, carbon, and iron targets, including radiative corrections. Preliminary comparisons with data simulated using the GENIE generator are made.

        MINERvA hadron testbeam results 1h 30m
        We exposed a scaled-down version of the MINERvA detector to a beam of pions, kaons, and protons with momenta between 400 and 2000 MeV. These data are important for constraining the detector response to hadrons for our neutrino analyses in many respects: calorimetry, tracking, and PID response, and to constrain detector and Geant4 model uncertainties. For this, we built and operated a new tertiary beamline at the Fermilab Test Beam Facility in Summer 2010, and operated our detector with reconfigurable absorber in a tracker + ECal and ECal + HCal configurations. This poster will include the preliminary results from the analysis of calorimetric response in the ECal + HCal configuration.

        MINERvA Neutrino Detector Calibration 1h 30m
        Current and future neutrino oscillation experiments depend on precise knowledge of neutrino-nucleus cross-sections. MINERvA is a neutrino scattering experiment at Fermilab, studying the interactions of muon neutrinos and antineutrinos with various nuclear targets. In order to make these measurements, it is vital that we carefully calibrate our detector. This poster explains the various in situ calibration techniques and cross-checks used by MINERvA to convert our electronics output to absolute energy deposition values.

        Phenomenological investigation of muon neutrino disappearance via CC interaction 1h 30m
        Experimental evidences showed that the time evolution of a particular neutrino flavor state can produce the transition to a different flavor state, a phenomena called neutrino oscillation. In this work we aim to study the oscillation model by doing a phenomenological analysis using the MINOS (Main Injector Neutrino Oscillation Search) published data. We first review the muon neutrino CC disappearance results from SK, K2K and MINOS, then we show some quality tests of the data extracted, including a comparison with the allowed region contour plots. We also show preliminary results of our analysis including 3-flavor oscillation model. This study could contribute to test different sub-dominant models, such as decay and decoherence, trying to improve the oscillation model.

        Predictions for hadron polarizations and left-right asymetry in inclusive reactions involving photons 1h 30m
        A phenomenological model which has had some success in explaining polarization phenomena and left-right asymmetry in inclusive proton-proton scattering is considered for reactions involving photons and, hopefully, neutrinos. In particular, the reactions (a) gamma + p -> H + X, (b) gamma + p(up) -> pi(+-) = X, and (c) p(up) + p -> gamma + X are considered where gamma = resolved photon, and hyperon H = Lambda0, Sigma+-, etc. Predictions for hyperon polarization in (a) and the asymmetry (in (b) and (c)) provide further tests of this particular model.

        Present Status of the Neutrino Angra Project 1h 30m
        We will present the status of the Neutrino ANGRA project, aimed at developing an antineutrino detector for monitoring nuclear reactor activity. The Angra experiment will be deployed at the Brazilian nuclear power plant Angra II. A water Cherenkov detector of one ton target will be placed in a commercial container next to the reactor containment, about 30 m from the reactor core. The 4 GW thermal power of the Angra II reactor will provide a few thousand antineutrino inverse beta decay interactions per day. The detector will consist of three subsystems: 1) a muon veto placed in the outer most detector layer; 2) a neutron shield 30cm thick consisting of water; 3) a central detector consisting of an inner neutron shield (20cm) and a one ton central target both filled with a mixture of water and 0.2% of gadolinium.The main challenge of the experiment will be to overcome the very high cosmic ray induced background at sea level, consisting of muons, neutrons, gammas, protons, pions, positrons and electrons.We have simulated the signal and background events at the expected rates and used a Mixer program to organize them in temporal order, simulating in this way the real events in the Angra detector. We will present the analysis strategy to overcome the background and extract the number of antineutrino events.

        RCNP E398 experiment C,O(p,p') to measure \gamma ray branching ratio (E>5MeV) from the giant resonances of carbon and oxygen in relation to the \gamma ray production in C,O(\nu,\nu'). 1h 30m
        We plan to measure the branching ratios of \gamma-ray emission (E_\gamma >5 MeV) from giant resonance of ^16O and ^12C, as the functions of excitation energy (E_x). This measurement will provide the fundamental and important information not only for the \gamma-ray production from primary neutral-current neutrino-oxygen (-carbon) interactions but also for that from the secondary hadronic (neutron-oxygen and -carbon) interactions. The understanding of the \gamma-ray production will introduce a new neutrino detection method to Supernova neutrino physics and Neutrino oscillation physics. In the second stage, we would like to perform O,C(He,t) (T=1) experiment at 0 degrees to continue the systematic study of spin-isospin response through the measurement of the \gamma-ray production with oxygen and carbon nuclei.

        Simulation of atmospheric temperature effects on cosmic ray muon flux 1h 30m
        The collision between a cosmic ray and an atmosphere nucleus produces a set of secondary particles, which will decay or interact with other atmosphere elements. This set of events produced by a primary particle is known as an extensive air shower (EAS) and is composed by a muonic, a hadronic and an electromagnetic component. The muonic flux, produced mainly by pion and kaon decays, has a dependency with the atmosphere’s effective temperature: an increase in the temperature results in a lower density profile, which decreases the probability of pions and kaons to interact with the atmosphere and, consequentely, resulting in a major number of meson decays. Such correlation between the muon flux and the atmosphere’s effective temperature was measured by a set of experiments such as AMANDA, Borexino, MACRO and MINOS. This phenomena can be investigated by simulating the final muon flux produced by two different parameterizations of the isothermal atmospheric model in CORSIKA, where each parameterization is described by a depth function which can be related to the muon flux in the same way that the muon flux is related to the temperature. This research checks the agreement among different high energy hadronic interaction models and the physical expected behavior of the atmosphere temperature effect by analysing a set of variables, such as the height of the primary interaction and the difference in the muon flux.

        Study of Quasi-elastic interactions using the NOvA Near Detector Prototype 1h 30m
        NOvA is a 14 KTon long-baseline neutrino oscillation experiment currently being installed in the NUMI off-axis neutrino beam produced at Fermilab. A 222 Ton prototype NOvA detector (NDOS) was built and operated in the neutrino beam for over a year to understand the the response of the detector and its construction. Muon neutrino interaction data collected in this test are being analyzed to identify quasi-elastic charge-current interactions and measure the behavior of the Quasi-elastic muon neutrino cross section. The status of these quasi-elastic studies in NDOS will be shown.

        Systematic muon capture rates in PQRPA 1h 30m
        In this work we performed a systematic study of the inclusive muon capture rates for the nuclei 12C, 20Ne, 32Mg, 28Si, 40Ar, 52Cr, 54Cr, 56Fe, and 58Ni using the Projected Random Quase-particle Phase Approximation (PQRPA) as nuclear model. The theoretical results of the capture rates within the PQRPA have been compared with those obtained in other works using other models. We reckon that the comparison between theory and data for the inclusive muon capture is not a fully satisfactory test on the nuclear model that is used. The exclusive muon transitions are more robust for such a purpose.

        Understanding the NuMI Flux for MINERvA 1h 30m
        The Neutrinos at the Main Injector (NuMI) beamline delivers intense neutrino and anti-neutrino beams in an energy range of 2-20 GeV. Understanding these fluxes is crucial for measuring absolute cross sections in MINERvA. Three techniques for constraining these fluxes are being considered in MINERvA: in situ neutrino event rate measurements, external hadron production data and in situ muon flux measurements. This poster will present these three strategies and the status of each one.

        Weak interaction induced $\eta$-production off the nucleon 1h 30m
        $\eta$ production off the nucleon induced by (anti)neutrinos is studied at the low and intermediate energies for the ongoing and future neutrino oscillation experiments. The non-resonant terms are calculated using a microscopical model based on the SU(3) chiral Lagrangians. We consider $S_{11}$(1535) and $S_{11}$(1650) resonances. The vector part of the N-$S_{11}$ transition form factor has been obtained from the helicity amplitudes using MAID(2007) data, dipole form is taken for the axial form factor and the PCAC relation is used for the pseudoscalar form factor.

        νμ CCπ0 reaction in the Tracker of the ND280 detector in the T2K experiment 1h 30m
        Good knowledge of both inclusive and exclusive neutrino interaction cross sections is one of the key issues for a precise determination of the neutrino oscillation parameters in the T2K experiment.These studies are performed at the near detector (ND280). Its central tracker part equipped with a water target serves, among others, to study the νμ CCπ0 reaction. At the energies of the T2K neutrino beam its contribution to the total cross section is relatively large, so the reaction is a potential source of background for the quasi-elastic νμ CC reaction. Two different production mechanisms contribute: single pion resonanse production and DIS. In addition, FSI has to be considered. Thus, the analysis of the νμ CCπ0 reaction aims also at a better tuning of the MC models used to describe neutrino interactions in T2K. This poster describes the reconstruction and selection criteria leading to the determination of the exclusive cross section for the νμ CCπ0 reaction.
