Description
Summary:The basic task of the Large Volume Detector LVD situated at the underground Gran Sasso National Laboratory (Italy) is the search for neutrino bursts from gravitational stellar collapses in our Galaxy. At present, the algorithm for determining neutrino bursts has been developed. It is based on the identification of event clusters in fixed time intervals, special attention is paid not only to the inverse β decay reaction which has a characteristic signature, but also to the neutrino-iron interaction. The data for of 3.5 years of LVD operation have been processed. No candidates for neutrino bursts are found.
