Selection techniques of neutrino-induced cascades in the Baikal-GVD neutrino telescope

Popis výsledku v původním jazyce

The neutrino telescope Baikal-GVD (Gigaton Volume Detector) has been designed to search for high-energy neutrino cosmic sources. It is located in pure water of Lake Baikal at a depth of 1366 m. Currently (year 2022) Baikal-GVD comprises 2880 optical modules divided to 10 independently operating clusters. Optical modules detect flashes of Cherenkov light from secondary charged particles induced in interactions of neutrinos with matter. Some charged and neutral current neutrino interactions lead to hadronic or electromagnetic cascade events. Apart from the neutrino cascades, the cascade-like light topologies can be also induced along the muon tracks. These event signatures, referred to as background cascades arise from the discrete stochastic energy losses of the muon. The cascades produced along the atmospheric muon bundles constitute the main background in neutrino cascade channel. In this paper, a developed, optimized, and tested algorithm for suppression of the background cascades is presented.
