Search for Neutrino–Gravitational Correlations on the OGRAN and BUST Underground Detectors
摘要
Abstract
The strategy for detecting collapsing stars in the Galaxy using a pair of instruments including the OGRAN optoacoustic gravitational detector and the BUST neutrino scintillation telescope, located in the ground laboratories of the Baksan Neutrino Observatory, Institute for Nuclear Research, Russian Academy of Sciences, is discussed. A key element of the strategy is the search for correlated responses from both detectors, the so-called search for neutrino-gravitational correlations. The efficiency of various algorithms for joint data processing, including analysis of the CH1987A event, is assessed. The processing technique is illustrated using the current output signals of the mentioned instruments.
