Georgy Raikov (NRC “Kurchatov Institute”) "Search for the diffuse supernova neutrino background and solar hep-neutrinos in the Borexino experiment"
The report is devoted to the study of solar hep-neutrinos and diffuse supernova neutrino background (DSNB) in the Borexino experiment. The peculiarities of studying solar hep-neutrinos, which have the highest energy and the lowest flux among all neutrinos from the Sun, will be discussed. Constraints on the hep-neutrino flux are presented, based on Borexino detector data on neutrino-electron elastic scattering and neutrino interaction with carbon nuclei.
The features of searching for DSNB by the Borexino detector are also discussed. For electron antineutrinos, for the first time the results were obtained in the previously unexplored by other detectors energy range of 1.8–8.3 MeV.
