micrOMEGAs:一个研究暗物质的工具

micrOMEGAs : a tool for dark matter studies

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

摘要:

micrOMEGAs是一种研究冷暗物质(DM)的工具,它是标准模型的一般扩展,具有类似R宇称的离散对称性,保证了最轻奇粒子的稳定性。该程序计算了DM残留物密度、DM在与直接探测有关的核上的弹性散射截面以及DM湮灭产生的正电子、反质子和光子的谱,包括带电宇宙射线的传播。新粒子的截面和衰变特性的相关对撞机的研究,包括以及从味部门的超对称模型的参数空间上的约束。

英文摘要:

micrOMEGAs is a tool for cold dark matter (DM) studies in generic extensions of the standard model with a R-parity like discrete symmetry that guarantees the stability of the lightest odd particle. The code computes the DM relic density, the elastic scattering cross sections of DM on nuclei relevant for direct detection, and the spectra of positrons, anti-protons and photons originating from DM annihilation including porpagation of charged cosmic rays. The cross sections and decay properties of new particles relevant for collider studies are included as well as constraints from the flavour sector on the parameter space of supersymmetric models.
