N operating neutrino telescopes in searching for a singnal of dark
matter weakly interacting massive particles (WIMPs).

a The opportunity for indirect signature as well as for direct detection of
WIMPs is coming from a drastical assumtion that WIMPs elastically in-
teract (via mass and spin) with ordinary baryonic matter [3, 4]. Since neu-
tralinos are a mixture of the respective partners of the electrically
