Abstract
Tokai-to-Kamioka (T2K) is a long baseline neutrino experiment which uses the proton beam at the Japan Particle Accelerator Research Centre (JPARC) to produce a beam of muon neutrinos and antineutrinos. T2K determines neutrino oscillation parameters of interest by comparing the measured neutrino rate and spectrum at a near detector complex, located at JPARC, and at SuperKamiokande, a water-Cherenkov detector, located 295 km away. T2K is currently undergoing major improvements: the JPARC neutrino beam is increasing in power, the Super-Kamiokande detector has been loaded with 0.02% of Gadolinium, enabling enhanced neutron tagging; and a significant upgrade of the ND280 near detector is scheduled for installation in 2022/23. These proceedings summarise T2K’s latest measurements of neutrino oscillations and detail some of the planned improvements, with particular focus on the upcoming near detector upgrade.
