Planck-scale effects on WIMP dark matter

Planck-scale effects on WIMP dark matter

There exists a widely known conjecture that gravitational effects violate global symmetries. We study the effect of global-symmetry violating higher-dimension operators induced by Planck-scale physics on the properties of WIMP dark matter. Using an effective description, we show that the lifetime of...
