“…Within this context, a presented selection technique that implements various selection methods for neutrino cascade events with multicluster search represents an improved version of the cascade selection algorithm [4]. The optimization was performed on the simulated data of background cascades from atmospheric muons atm and on signal cascades from atm and astro interactions.…”

“…The nTrackHits method selects hits with time residuals in the interval: 1 < − track < 2 , where is the OM hit time, 1 = −100 ns, 2 = 25 ns. The expected time track , when the OM is supposed to detect a hit from the muon track [4]. This method identifies the hits per event that fulfill the criteria for the muon track.…”

One of the light signatures in the Baikal-GVD neutrino telescope consists of hadronic and electromagnetic cascades produced by charged interactions of electron and tau neutrinos. In the case of neutral current interactions, all flavors yield cascades. The background in the neutrino cascade channel arises mainly due to discrete stochastic energy losses produced along atmospheric muon tracks. In this contribution, a developed algorithm for the cascade event selection is presented.

Baikal-GVD (Gigaton Volume Detector) is a neutrino telescope installed at a depth of 1366 m in Lake Baikal. The expedition of 2023 brought the number of optical modules in the array up to 3492 (including experimental strings). These optical modules detect the Cherenkov radiation from secondary charged particles coming from the neutrino interactions. Neutrinos produce different kinds of topologically distinct light signatures. Charged current muon neutrino interactions create an elongated track in the water. Charged and neutral current interactions of other neutrino flavors yield hadronic and electromagnetic cascades. The background in the neutrino cascade channel arises mainly due to discrete stochastic energy losses produced along atmospheric muon tracks. In this paper, a developed algorithm for the cascade event selection is presented.
