Ciro Riccio (Stony Brook), "T2K Latest Results"
T2K (Tokai to Kamioka) is a long-baseline neutrino oscillation experiment designed to measure neutrino flavor oscillations. A neutrino beam peaked around 0.6 GeV is produced in Tokai (Japan) 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. One of the primary goals of T2K is the search for Charge-Parity (CP) violation in neutrino oscillations. The observation of CP violation in the lepton sector could provide important clues to the origin of the matter-antimatter asymmetry of the Universe, one of the most fundamental open questions in modern physics. To enhance its sensitivity, T2K has recently upgraded both its neutrino beamline to achieve higher beam power and its off-axis near detector complex to improve constraints on the dominant systematic uncertainties affecting oscillation measurements. In this seminar, an overview of the latest T2K neutrino oscillation results will be presented, together with the current status of analyses using data collected with the upgraded beam and near detector. Since the beginning of operations, T2K has produced a wealth of important results and is now entering its final phase of data taking. Its scientific legacy will play a crucial role in shaping the next generation of long-baseline neutrino oscillation experiments.
