论文摘要
我们将不对称的暗物质遗物密度和Sommerfeld增强的分析扩展到了介体大规模的情况下。在不对称的暗物质模型中，假定不对称的暗物质将其与标量或矢量玻色子搭配在一起。不对称的暗物质an灭横截面通过sommerfeld效应增强，由于不对称暗物质粒子和抗颗粒的波函数的扭曲而存在。讨论了Sommerfeld增强对不对称暗物质颗粒和抗粒子的遗物密度的影响。当Sommerfeld的增强增强歼灭横截面时，还要探测动力学脱钩对遗物密度的影响。最后，通过使用暗物质的观察数据给出了对参数空间的约束。
We extend the analysis of asymmetric Dark Matter relic density with Sommerfeld enhancement to the case where the mediator is massive. In asymmetric Dark Matter models, the asymmetric Dark Matter is assumed to couple to light scalar or vector boson. Asymmetric Dark Matter annihilation cross section is enhanced by the Sommerfeld effect which exists due to the distortion of wavefunction of asymmetric Dark Matter particle and anti--particle by long--range interactions. The impacts of Sommerfeld enhancement on the relic densities of asymmetric Dark Matter particle and anti--particle are discussed. The effect of kinetic decoupling on the relic density is also probed when the annihilation cross section is enhanced by Sommerfeld enhancement. Finally, the constraints on the parameter space is given by using the observational data of Dark Matter.
