Eventi INFN Sezione di Bari

Neutrino physics with accelerator neutrino beams is on the verge of a new era, driven by the imminent construction of second-generation experiments such as Hyper-Kamiokande and DUNE, expected to come online within the next few years. This presentation will provide an overview of our current understanding of neutrino oscillations and of the key open questions that Hyper-Kamiokande is designed to address.

The experiment is based on a multi-megawatt, high-intensity muon-neutrino beam produced on the Pacific coast of Japan and directed toward a newly constructed water Cherenkov detector located 295 km away. The far detector will have an unprecedented fiducial mass of approximately 260 kton and is currently in a crucial phase of construction, with Italian institutes playing a major role in its realization.

Hyper-Kamiokande will, for the first time, make it possible to probe the value of the so-called CP-violating phase with high statistical precision, shedding light on the symmetry properties of neutrino and antineutrino oscillations. Owing to its large mass, the experiment will also enable the study of neutrinos from supernova explosions as distant as the Andromeda galaxy, as well as searches for proton decay with sensitivities far beyond current limits, potentially leading also to unexpected discoveries.
