Abstract

First, singlet dark matter annihilation into pair charged fermions and pair bosons was studied to the first order of non-commutativity parameter in perturbative model. Our results are different from the results reported in some previous studies. Then the problem is formulated in -exact non-commutative space-time and non-perturbative model, then the exact results are presented
