Query: Signature of relic heavy stable neutrinos in underground experiments   Considering heavy stable neutrinos of 4th generation we calculate the relic
density of such neutrinos in the Universe. Taking into account the condensation
of heavy neutrinos in the Galaxy and applying the results of calculations to
experimental data from underground experiments on search for WIMPs in elastic
neutral current scattering on nuclei we found an exclusion region of neutrino
mass 60 GeV < m < 290 GeV. The bounds obtained from present underground
experiments while confirming the previous bounds derived from analysis of
cosmic ray spectra are more relible ones. We discuss also the first indication
of elastic scattering induced by WIMP in DAMA experiment finding a very narrow
window of neutrino mass 45 GeV < m < 50 GeV compatible with the possible signal
rate in the detector.
