TeV particles as weakly unstable dark matter Academic Article uri icon

abstract

  • Particles of several TeV that remain from the Big Bang could comprise the cosmic closure density and, if unstable at the grand unification scale, they could provide the observed anomalous positron component in the cosmic radiation at 10\char21{}20 GeV. The model predicts a diffuse \ensuremath{\gamma}-ray signal that should stand out above the expected background above 10 GeV.
