Description
T2K is a long-baseline neutrino oscillation experiment taking data since
2010. A neutrino beam is produced at the J-PARC accelerator in Japan and is
sampled at a Near Detector complex 280 m from the
neutrino production point and at the far detector, Super-Kamiokande.
Beams predominantly composed of muon neutrinos or muon anti-neutrinos have been
produced by changing the currents in the magnetic focusing horns.
The additional neutrino-mode data collected with T2K in 2017 have doubled the statistics relative to previous analysis releases.
This presentation will show the most recent T2K oscillation results
obtained from a combined analysis of the entire available data set in the
muon neutrino and muon anti-neutrino disappearance channels, and in the electron neutrino and electron anti-neutrino appearance channels. Using these data, we measure four
oscillations parameters: $\sin{\theta_{23}}$, $\sin{\theta_{13}}$, $|\Delta
m^2_{32}|$ and $\delta_{CP}$, as well as the mass ordering.
