Supernova neutrinos search with the LVD experiment: The 2019 update

Contributo in Atti di convegno
Data di Pubblicazione:
2019
Abstract:
The Large Volume Detector (LVD) at the INFN Gran Sasso National Laboratory, Italy, is a neutrino observatory designed to study low energy neutrinos from gravitational stellar collapses. The detector, 1 kton of liquid scintillator, is sensitive to core-collapse supernovae via neutrino burst detection with 100% efficiency over the Galaxy. In this paper we summarize the results of the last run, lasting from 2014, January 1st to 2019, June 6th for a total live time of 1978 days. In the lack of a positive observation in this data set and including all previously published results since 1992 for a total of 9313 days, the upper limit on the rate of core collapse and failed supernova explosions out to distances of 25 kpc is 0.09 year-1 at 90% c.l..
