Results and Prospects of T2K

Abstract

T2K is a neutrino oscillation experiment with a 295 km long baseline between the far detector, Super-Kamiokande, and a suite of near detectors to study ${\nu }_{\mu }/{\bar{\nu }}_{\mu }$ disappearance and ${\nu }_e/{\bar{\nu }}_e$ appearance in a ${\nu }_{\mu }/{\bar{\nu }}_{\mu }$ neutrino beam produced at J-PARC. The experiment has excluded CP conservation in the three-neutrino oscillation model at $>90\%$ CL and precisely constrained the parameters $|\Delta m_{32}^2|$ and ${\sin }^2{\theta }_{23}$. This paper reports on the novelties of the most up-to-date 2022 analysis and the near-future prospects of T2K.
