Description
We report the results of a search for neutrino bursts from supernova
explosions with the Large Volume Detector (LVD) at the INFN Gran Sasso
National Laboratory.
LVD is sensitive to core-collapse supernova explosions via neutrino
outburst detection with 100% efficiency over our own entire Galaxy. No
evidence of supernova explosion is found over 7335 live days spanning
from June 1992 to December 2013. The 90% C.L. upper limit on the rate of
core-collapse supernova explosions out to distances of 25 kpc is found to
be 0.114 event/year.
