论文摘要
宇宙正电子异常仍未得到解释。用暗物质（DM）腐烂或歼灭的解释是这样做的主要尝试之一。但是，由于诱发伽马辐射的过度生产与宇宙伽玛背景相矛盾，因此他们遭受了缺点。在这样的过程中，最终状态辐射（FSR）在标准条件下（默认情况下）具有基本贡献。我们的小组阐述了以不同方式逃避这个问题的可能性。在这里，由于拉格朗日描述了DM粒子衰变的细节，我们继续将其中一个与抑制FSR的可能性有关。考虑到两个新的旋转器和标量循环。发现FSR抑制的效果是存在的，但在被考虑的情况下处于非常低的水平。
Cosmic positron anomaly is still not explained. Explanation with dark matter (DM) decay or annihilation is one of the main attempts to do it. But they suffer with shortcoming as overproduction of induced gamma-radiation which contradict to cosmic gamma-background. Final state radiation (FSR) in such processes is supposed under standard conditions (by default) to have the basic contribution in it. Our group elaborates possibility to evade this problem in different ways. Here we continue one of them connected with possibility of suppression of FSR due to specifics of Lagrangian describing DM particle decay. Loop through two new spinors and scalar is considered. Effect of FSR suppression is found to be existing but at the very low level in the considered case.
