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.

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

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...

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...

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...

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...

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...

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...

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...

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...
