micrOMEGAs4.1: two dark matter candidates

G. Belanger, F. Boudjema, A. Pukhov, A. Semenov

摘要:

micrOMEGAs是一种在标准模型的一般扩展中计算暗物质可观测量的代码。这个版本的micrOMEGAs包括一个广义的玻尔兹曼方程,考虑到两个暗物质候选者的可能性。修改的遗迹密度计算,包括两个DM部门之间的相互作用,以及半湮灭。直接和间接检测中的DM信号也被计算。一个扩展的标准模型的两个标量双峰和一个单作为一个例子。

英文摘要:

micrOMEGAs is a code to compute dark matter observables in generic extensions of the standard model. This version of micrOMEGAs includes a generalization of the Boltzmann equations to take into account the possibility of two dark matter candidates. The modification of the relic density calculation to include interactions between the two DM sectors as well as semi-annihilation is presented. Both DM signals in direct and indirect detection are computed as well. An extension of the standard model with two scalar doublets and a singlet is used as an example.
