作为CP破坏源的暗光子和可见光子

Dark and Visible Photons as Source of CP Violation

J. Gamboa, F. Mendez

摘要:

假设光子的产生主要由两种过程控制,第一种是由于常规的动力学混合项,第二种是由于动力学混合项破坏了暗光子和可见光子之间的CP对称性,讨论了星系中心的过量γ辐射问题.暗扇区和可见扇区之间的CP破坏对称性不被禁止,并且原则上可以被认为是CP破坏的附加源。计算了暗光子和可见光子之间的转换几率,并对两种过程进行了比较。违反CP的过程不太重要,但对过量伽马辐射的贡献很大。

英文摘要:

The problem of excess gamma radiation in the center of galaxy is discussed assuming that the photon's production is dominated by two kinds of processes, the first one due to the conventional kinetic mixing term and, secondly, due to a kinetic mixing term violating the CP symmetry between dark and visible photons. The CP violation symmetry between dark and visible sectors is not forbidden and, in principle, could be considered as an additional source of CP violation. The conversion probability between dark and visible photons is calculated and compared between both processes. The processes violating CP are less significant but contribute non-trivially to the excess gamma radiation.
