Накратко на български

Взаимодействията на неутрино се изучават чрез огромни резервоари с вода, които засичат частици от космически източници като свръхнови. Тези измервания помагат за разбирането на фундаменталните елементи на материята и физичните процеси в Universe.

From Super-Kamiokande to Hyper-Kamiokande

SK2HK, Super-Kamiokande (SK) to Hyper-Kamiokande (HK), is part of the ongoing global efforts to understand the most fundamental elements of matter and their interactions. We aim to investigate neutrino interactions using the existing experimental facility in Japan, the SK detector located in the Kamioka Observatory (Gifu Prefecture) and owned by the partner of this Project: the Institute for Cosmic Ray Research of the University of Tokyo (ICRR). SK is a very big (50000 tons) instrumented pure water tank that measures the radiation Cherenkov generated by energetic charged particles traveling along its inside. External particles, for instance neutrinos, might interact with particles in the detector. The final state interaction consists of newer particles, many of them charged and therefore able to be measured by SK. From those measurements we can learn about the interaction process and the fundamental physics behind. The SK detector is located underground, approx. 1000 m overburden, to reduce the flux from cosmic ray muons arriving to the detector. We have upgraded SK (to SuperK-Gd) by dissolving a salt of Gd on its water. The very large neutron capture cross section of the Gd, with photon emission in the process (approx. 8 MeV total energy) allows precise identification of neutrons which will be key in the discovery of the DSNB (Diffuse Supernova Neutrino Background). We are working on the new generation neutrino experiment, the HK project. It consists of a) a huge "far detector", SK-like device (approx. 200000 tons), being built also at Kamioka, b) an upgraded neutrino beam made at JPARC (Japan Proton Accelerator Research Complex, Ibaraki prefecture) and directed to Kamioka, and c) an additional "near detector", IWCD (Intermediate Water Cherenkov Detector), to measure with unprecedented precision the characteristics of the neutrino beam at generation. SK2HK addresses fundamental problems in Physics at different stages, by analyzing the SK data, and by designing and building HK-FD and IWCD. These are neutrino oscillations, the search for dark matter, the physics of nearby galactic supernova, the DSNB, and Grand Unification. The collaborative work with the leaders of the field (ICRR holds two Nobel Prices in Physics: M. Koshiba in 2002, and T. Kajita in 2015) provides us with invaluable experience.

Цел на проекта

The study of the neutrino properties and interactions has been key in the development of the Standard Model of fundamental interactions and it is providing first clues on the understanding of its deeper foundations. In this aspect the Super-Kamiokande (SK) detector (ICRR, U. Tokyo, Japan) for many years has played a crucial role. It contributed to the discovery of oscillations of atmospheric neutrinos, thus establishing their 'massive' character. Because of this discovery, Takaaki Kajita, the “person in charge of this proposal” from our main Third Country partner ICRR, was awarded with the Nobel Prize in Physics 2015.With SK2HK we aim to continue the very successful SKPLUS, through extension of participation of European institutes in the state-of-the-art experimental program related to the SK, the SK-Gd and the Hyper-Kamiokande (HK) experiments. We want to gain insight and even discover the hypothesized charge-parity violation in the leptonic sector with SK and the future HK. We want to discover the ""Diffuse Neutrino Supernova Background"" with SK-Gd and to explore in depth the Grand Unification with SK and the future HK. Those measurements are key to the complete understanding of the most fundamental concepts of Physics.An important aspect of this proposal is significant amount of hardware R&D related to HK, especially given the decision to start HK construction in 2020. Timely finalization of these activities is crucial to the success of HK and requires even closer cooperation with our partners. Given the uniqueness of the technologies that are being developed, it is efficient to do some work at the location where most of the infrastructure needed for the R&D is. In this project those are the ICRR of the Univ. of Tokyo and the TRIUMF laboratory in Canada, as well as several European laboratories, incl. the applying institutions. The proposed secondment program offers a unique opportunity to fulfill these goals while working with World leading experts.""
