On the correlation between Mont Blanc and Baksan underground detectors in February 1987

According to the author, there is a correlation directly between the Mont Blanc (LSD) and Baksan data, two quite similar underground scintillation detectors. The idea is: if something really happens that activates the gravitational antennas (G.A.) signal and that, after 1.2 s, gives a signal in a particular scintillator, then there should be a chance to observe a quasi-simultaneous signal in another, possibly very distant scintillator. The big distance between the Baksan and LSD detectors should exclude the common electrical power supply as a possible source of correlation. Another advantage of the suggested search could be a simplicity of statistical analysis when the duration of the signal (in the scintillation counter) is much less than the correlation time interval (1 s). In this report, the author discusses both positive and negative evidence concerning the LSD-Baksan correlation
