Abstract
The T2K (Tokai-to-Kamioka) experiment probes the mass differences and mixing of neutrinos through measurements of neutrino
oscillations. A beam of muon neutrinos or muon antineutrinos is generated at the J-PARC proton
accelerator on the east coast of Japan, and the beam’s composition after oscillations is measured 295 km away in the
Super-Kamiokande detector. The transition of muon neutrinos and antineutrinos to other flavors
is governed by neutrino mixing and
mass parameters, including the phase $\delta_{CP}$, which determines the amount of CP violation in neutrino
mixing. Previous measurements from T2K have shown a strong constraint on $\delta_{CP}$ with the exclusion
of a significant fraction of $\delta_{CP}$ values at 3$\sigma$ confidence. Here, we present the latest results from T2K
with data collected through 2020.
