11:45 → 12:40 T2K latest results and future prospects in neutrino oscillations

T2K (Tokai to Kamioka) is a Japan-based long-baseline neutrino oscillation experiment designed to measure (anti-)neutrino flavor oscillations. A neutrino beam is produced in Tokai and directed toward the water Cherenkov detector Super-Kamiokande, which is located 295 km away. A complex of near detectors is located at 280 m and is used to constrain the flux and cross-section uncertainties. T2K has produced a wealth of significant results and holds exciting prospects for the future. One of the most promising activity of T2K is the investigation of CP (Charge-Parity) violation in neutrino oscillations. The pursuit of CP violation could unveil the enigmatic matter-antimatter asymmetry in the universe, a cornerstone in understanding its evolution. To achieve this goal, T2K is taking data with a neutrino and antineutrino enhanced beam investigating asymmetries in the electron neutrino and antineutrino appearance probabilities. One of the largest systematic uncertainties affecting neutrino oscillation measurements comes from limited knowledge of (anti-)neutrino-nucleus interactions. T2K has a wide range of neutrino cross-section measurements using detectors in its near detector complex. In this seminar an overview of the latest T2K results are presented, as well as its future prospects, which are characterized by an intense program of upgrades. T2K legacy will undoubtedly be instrumental in guiding the path of future long-baseline neutrino oscillation experiments. Finally, a general overview of the future endeavors in neutrino oscillation will be discussed.
