چکیده مقاله:

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have neither approved nor rejected. Some complicated models offer many parameters that must be determined. Among these models, the singlet scalar dark matter model is the simplest one that contains just two free parameters to specify. In this paper, we study the singlet scalar dark matter in the noncommutative space, give the scalar dark matter and higgs lagrangian to find their coupling in noncommutative space-time and calculate the cross-section of the scalar dark matter pair annihilation to becoming the standard model particles. It must be noted  that there is one extra coupling to explain the dark matter annihilation to becoming  the standard model particles in the noncommutative space-time. We investigate the parameter space using the constraint of the  thermal average of annihilation cross-section by the velocity. This is the first research on  the dark matter annihilation to becoming the standard model particles through the higgs channel in the noncommutative space.

Singlet scalar dark matter effects on Higgs boson driven inflation

A minimal candidate for dark matter is provided by a stable standard model singlet hermitian scalar field. The quantum mechanical effects of this singlet are explored in a model where the standard model Higgs boson has a large non-minimal coupling to the Ricci scalar and plays the role of the inflaton. Imposition of the slow roll inflation cosmological constraints restricts the allowed values o...

Scalar Dark Matter From Theory Space

The scalar dark matter candidate in a prototypical theory space little Higgs model is investigated. We review all details of the model pertinent to dark matter. We perform a thermal relic density calculation including couplings to the gauge and Higgs sectors of the model. We find two regions of parameter space that give acceptable dark matter abundances. The first region has a dark matter candi...

Singlet fermionic dark matter

We propose a renormalizable model of a fermionic dark matter by introducing a gauge singlet Dirac fermion and a real singlet scalar. The bridges between the singlet sector and the standard model sector are only the singlet scalar interaction terms with the standard model Higgs field. The singlet fermion couples to the standard model particles through the mixing between the standard model Higgs ...

Scalar Dark Matter candidates

We investigate the possibility that Dark Matter could be made of scalar candidates and focus, in particular, on the unusual mass range between a few MeV’s and a few GeV’s. After showing why the Lee-Weinberg limit (which usually forbids a Dark Matter mass below a few GeV’s) does not necessarily apply in the case of scalar particles, we discuss how light candidates (mdm < O(GeV) ) can satisfy bot...
