暗物质湮灭成双光子截面的一般计算

General calculation of the cross section for dark matter annihilations into two photons

Camilo Garcia-Cely, Andres Rivera

摘要:

假设基本模型满足可重整化性和CP守恒等一般性条件,我们计算了任意自共轭暗物质湮灭为两个光子的非相对论单圈截面.我们通过对所有可能的单圈图进行仔细分类,并从中读出暗物质与圈中运行的粒子的相互作用来实现这一点。我们的方法是通用的,并导致相同的结果在文献中发现流行的暗物质候选人,如中性伴子的MSSM,最小的暗物质,惰性希格斯和卡鲁扎-克莱因暗物质。

英文摘要:

Assuming that the underlying model satisfies some general requirements such as renormalizability and CP conservation, we calculate the non-relativistic one-loop cross section for any self-conjugate dark matter particle annihilating into two photons. We accomplish this by carefully classifying all possible one-loop diagrams and, from them, reading off the dark matter interactions with the particles running in the loop. Our approach is general and leads to the same results found in the literature for popular dark matter candidates such as the neutralinos of the MSSM, minimal dark matter, inert Higgs and Kaluza-Klein dark matter.
