In order to achieve the ambitious goal of characterising neutrino flavour oscillations with percent-level precision, it is critical for current and future long-baseline neutrino oscillation experiments to substantially reduce existing systematic uncertainties. The most challenging of such systematic uncertainties is related with the modelling few-GeV neutrino-nucleus interactions.
To...
Knowledge of neutrino interaction cross-sections are critical for accurately carrying out neutrino oscillation measurements. However, current models do not fully agree with data, requiring every experimental collaboration to choose the best available models, adjust them as appropriate, and assign sufficient systematic uncertainties before any oscillation analysis can take place. This talk...
The high statistics and excellent resolution capabilities of DUNE's $^{40}$Ar detector will allow us to make precise studies about phenomena that have, until now, seemed too complex to measure, like tau neutrinos $(\nu_{\tau})$ detection and therefore, provide a completion of the 3-flavor neutrino paradigm. Quasi-elastic scattering (QE), $\Delta$ resonance production (RES), and deep inelastic...
Simulation plays a critical role in neutrino experiments. But for a variety of reasons no simulation is perfect, and experiments must confront discrepancies between simulated predictions and their own measurements and observations. This inevitably leads to the need to tune the simulation in order to obtain robust and reasonable systematic uncertainties in analyses. In this talk I give an...
The Short-Baseline Near Detector (SBND) will be one of three Liquid Argon Time Projection Chamber (LArTPC) neutrino detectors positioned along the axis of the Booster Neutrino Beam (BNB) at Fermilab, as part of the Short-Baseline Neutrino (SBN) Program. The detector is currently in the construction phase and is anticipated to begin operation in 2023. SBND is characterized by superb imaging...
The ICARUS collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratories studying neutrino oscillations with the CNGS neutrino beam from CERN, and searching for atmospheric neutrino interactions. ICARUS performed a sensitive search for LSND-like anomalous νe appearance in the CNGS beam, which contributed to the constraints on the...
SBND is a 112-ton liquid argon time projection chamber located on the Booster Neutrino Beam at Fermi National Accelerator Laboratory, and is the near detector of the Short-Baseline Neutrino program. The primary goals of SBND are to provide flux constraints for sterile neutrino searches, conduct world-leading neutrino cross section measurements on argon, and perform beyond the Standard Model...
Various short-baseline neutrino oscillation experiments have yielded unexpected results, which hint at the existence of light sterile neutrinos. IceCube has performed a unique search for sterile neutrinos by exploiting matter-enhanced resonant oscillations, which can be probed using atmospheric and astrophysical neutrinos in the TeV energy regime. The analysis uses the world’s largest sample...
NOvA is a long-baseline neutrino experiment optimised for studying neutrino oscillations in the NuMI beam. The experiment consists of two functionally identical liquid scintillator detectors at baselines of 1km and 810km, with the latter placed 14.6 mrad from the beam’s central axis.
This talk summarises beyond-standard-model neutrino oscillation results from NOvA, including the recent...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long baseline neutrino oscillation experiment. DUNE will make precise measurements of neutrino oscillations, which will enable a definitive determination of the neutrino mass ordering, and a high potential to discover charge-parity violation in neutrinos. DUNE will use the most intense accelerator neutrino beam and employ...
The Short Baseline Near Detector (SBND), a 112-ton liquid argon time projection chamber, is the near detector of the Short Baseline Neutrino program at Fermilab. SBND has the characteristic of being remarkably close (110 m) to the neutrino source and not perfectly aligned with the neutrino beamline, in such a way that the detector is traversed by neutrinos coming from different angles with...
T2K is a long baseline neutrino experiment which exploits a neutrino and antineutrino beam at JPARC to perform precision measurements of atmospheric parameters $\Delta m^{2}_{32}$, $\sin^2(\theta_{23})$ and to provide 3$\sigma$ exclusion for some intervals of the CP-violating phase $\delta_{CP}$.
The latest results of the measurement of oscillation parameters will be presented, the main...
Neutrino oscillation physics has now entered the precision era. In parallel with needing larger detectors to collect more data, future experiments further require a significant reduction of systematic uncertainties with respect to what is currently available. In the neutrino oscillation measurements from the T2K experiment, the systematic uncertainties related to neutrino interaction cross...
Long-baseline neutrino oscillation experiments rely on detailed models of neutrino interactions on nuclei. These models constitute an important source of systematic uncertainty, partially because detectors to date have been blind to final state neutrons. Three-dimensional projection scintillator trackers comprise components of the near detector of the next generation long-baseline neutrino...
Hyper-Kamiokande (Hyper-K) is the next generation water-Cherenkov neutrino experiment, building on the success of its predecessor Super-Kamiokande. To match the increased precision and reduced statistical errors of the new detectors, improvements to event reconstruction and event selection are required to suppress backgrounds and minimise systematic errors. Machine learning has the potential...
The IceCube Neutrino Observatory is a Cherenkov detector deployed over a cubic kilometer deep within the South Pole ice. The DeepCore subdetector is built in the lower center of the array and more densely configured, improving the reconstruction performance of neutrinos at the GeV-scale, where atmospheric neutrino oscillations can be studied. Convolutional neural networks (CNN) are used to...
Super-Kamiokande has observed boron-8 solar neutrino recoil electrons at kinetic energies as low as 3.49 MeV to study neutrino flavor conversion within the sun. At SK-observable energies, these conversions are dominated by the Mikheyev–Smirnov–Wolfenstein effect. An upturn in the electron survival probability in which vacuum neutrino oscillations become dominant is predicted to occur at lower...
The ProtoDUNE-SP Liquid Argon Time Projection Chamber is the prototype for the first far detector module of the Deep Underground Neutrino Experiment (DUNE). Convolutional Neural Networks have been developed and employed in the analysis of scientific data from ProtoDUNE, which exploits the high-resolution images and the fine details that the detector can capture. Despite these advantages, the...
The muon anomalous magnetic moment (g-2) measurement by the Fermilab National Accelerator Laboratory (FNAL-E989) is consistent with a previous experiment by the Brookhaven National Laboratory (BNL-E821), with a deviation from the SM prediction of 4.2 standard deviations. This discrepancy could lead to the discovery of unknown particles, and a completely different approach from previous...
The muon collider is an excellent prospect as a multi-TeV lepton collider, with the possibility for high luminosity and reach to 10 TeV or more. In order to realise such luminosity, high beam brightness is required. Ionisation cooling, which was demonstrated recently by the Muon Ionization Cooling Experiment (MICE), is the technique proposed to realise sufficient brightness. MICE demonstrated...
The Fermilab Muon Campus, repurposed Tevatron-era Antiproton Source facilities, is currently the home to the g-2 and Mu2e muon experiments. Collecting data since 2017, the g-2 experiment is currently running and will switch to a mu-minus mode before the Muon Campus transitions to Mu2e operation. Currently in the commissioning process, the Mu2e experiment is expected to begin calibration and...
Mu2e-II will probe new physics mass scales up to 105 TeV by utilizing an 800-MeV 100-kW proton beam with an upgraded Mu2e beamline and detector, to obtain a sensitivity of ~10-17 in measurements of mu to electron conversion. This sensitivity is enabled by the PIP-II SRF Linac, which can accelerate a 2-mA proton beam to a kinetic energy of 800 MeV (1.6 MW of beam power); Mu2e-II will use a...
The Mu2e experiment will search for charge-lepton flavor violating (CLFV) muon to electron conversion. The signal for this process is a monoenergetic electron, and so a precise momentum measurement of the outgoing electron is required in order to reach the target 90% C.L. sensitivity of 8x10^-17. This is achieved in Mu2e using a low-mass cylindrical straw tracker operated in vacuum, consisting...
The Mu2e experiment will search for the charged-lepton flavor violating neutrino-less conversion of a negative muon into an electron in the presence of a nucleus. The experiment's goal is to improve the previous upper limit by four orders of magnitude. Any observation of this process is a clear sign of new physics. The single 105-MeV electron that results from this process can be mimicked by...
The COMET experiment aims to search for a muon to electron conversion with a single event sensitivity of $3\times10^{-15}$ in its Phase-I in order to explore new physics beyond the Standard Model. In the experiment, a high multiplicity environment is expected around the detector. Many accidental hits may cause a high fake trigger rate that cannot meet the DAQ capability, less than 13 kHz.
