摘要：

Superheavy (M> 10(10)) GeV) particles produced during inflation may be the dark matter. independent of their interaction strength. Strongly interacting superheavy particles will be captured by the Sun. and their annihilation in the center of the Sun will produce a flux of energetic neutrinos that should be detectable by neutrino telescopes, Depending on the particle mass, event rates in a cubic-kilometer detector range from several per hour to several per year. The signature of the process is a predominance of tau neutrinos. with a relatively flat energy spectrum of events ranging from 50 GeV to many TeV, and with the mean energy of detected tau neutrinos about 3 TeV.
