Seminar topic: “JINR Participation in the Japanese Neutrino Program: from T2K to Hyper-Kamiokande. The T2K Project”

Speaker: V. Glagolev

Abstract:

The participation of the JINR group in a very successful Japanese experimental program on neutrino physics will be discussed — in the ongoing T2K-II experiment and the Hyper-Kamiokande project.

The already approved T2K-II experimental program will allow extending the T2K running time until 2026 and collecting statistics of up to 20×10²¹ protons on target to observe the CP violation with the 3σ significance or higher and to measure neutrino mixing parameters, Θ₂₃ and Λm²₃₂, with a precision of 1.7 % or better and 1%, respectively. In order to achieve these goals, upgrades of the J-PARC accelerator complex and ND280, the Near Detector, are being performed.

The DLNP contribution to modernization of ND280 will be considered, namely, to the creation of a new unique active target, consisting of ~ 2 million cubic scintillators, which makes it possible to reconstruct particle tracks in three projections. Plans for further participation in the T2K collaboration and in the Hyper-Kamiokande project will be discussed. The seminar is held in connection with the proposal to open the Project.
