The discovery of neutrino oscillations has established non-zero neutrino mass and implies new physics beyond the standard model to generate neutrino masses. T2K is a long baseline accelerator-based neutrino oscillation experiment in Japan, studying the oscillations of a muon (anti)neutrino beam. T2K is making world leading measurements of neutrino oscillation parameters, including the first...
Neutrino parent particles in atmospheric and accelerator-based neutrino experiments are produced in hadronic interactions. Tagging of individual neutrinos and their ancestors is currently not possible. Therefore, we rely on Monte Carlo models and available hadron production data to predict neutrino fluxes. Without additional hadron production measurements, many neutrino measurements such as...
Machine learning has the potential to enhance the sensitivities of water Cherenkov detectors by improving the event reconstruction to suppress backgrounds and systematic uncertainties. Such improvements will be vital in achieving the precision measurements that current and next-generation water Cherenkov detectors are now aiming to perform.
This talk covers several areas where machine learning...
E61 is a proposed intermediate water Cherenkov detector (IWCD) for the future Hyper-Kamiokande (Hyper-K) long baseline neutrino experiment. The detector can be raised/lowered to span a continuous 1-4 degree off-axis range, relative to the neutrino beam centre, in order to make a novel measurement of the interaction rate as a function of neutrino energy. In this way E61 will constrain the...
The rare decay of the pion, to an electron and a neutrino, is an
important process in the Standard Model. The branching ratio of this
decay is one of the most precisely calculated weak interaction observ-
ables involving quarks. Measurement of the branching ratio provides
a sensitive test of lepton universality and tight constraints on many
new physics scenarios with mass reach up to 1000 TeV....
The future Hyper-Kamiokande neutrino oscillation experiment has the potential to discover CP violation in the lepton sector. In order to distinguish the small difference between neutrino and antineutrino oscillation, the experiment is designed to achieve an unprecedented statistical uncertainty of 3%. Correspondingly, a systematic uncertainty below this level is necessary for a robust and...
