Anapole Dark matter in the standard model extension and non-commutative standard model

Abstract

In the ADM the dark matters interact with the ordinary matters exclusively through the electromagnetic anapoles. Meanwhile, the only allowed electromagnetic form factor for the spin 1/2 Majorana fermions is the anapole one. We study the electromagnetic interaction of the Majorana neutrinos in non-commutative standard model (NCSM) and the Lorentz violated extension of the standard model (SME). Consequently, we obtain the anapole form factors in the both models. Comparing the obtained results in the SME with the experimental data only put a bound on d‎00‎-parameter among the SME- parameters which is of the order of 0.04. We estimate a bound of the order of 0.5 TeV on the parameter of non-commutativity.
