DESCRIPTION:Speakers: Vsevolod Ashikhmin (INR RAS)\nThe Large Volume Detec
 tor located in the Gran Sasso Laboratory\, Italy\, has been operating in t
 he stellar core collapse neutrino search program since 1992. Based on 32 y
 ears of detector data\, an experimental constraint on the frequency of neu
 trino bursts from gravitational collapses of stars in the Galaxy has been 
 obtained: less than 1 event in 13.9 years at a 90% confidence level. At an
  average depth of 3650 m w.e.\, the detector registers atmospheric muons w
 ith an average energy of 280 GeV in the angular range of 0 – 90. The det
 ector background in the low-energy range from 0.5 to 3 MeV is the natural 
 radioactivity of the soil\, the iron structures of the detector\, and rado
 n decay products in the room air. Variations in gamma quanta and muons are
  continuously monitored as the detector background when searching for neut
 rinos from supernovae. The paper presents the latest results of the analys
 is of the experimental data from the LVD detector.\n\nhttps://indico.parti
