论文摘要

考虑了$ r^2 $修饰的重力中的宇宙加热。计算出针对不同衰减通道的粒子产生速率。研究了与典型的超对称性相互作用强度的冻结稳定遗物。结果表明,超对称性粒子的质量的边界使它们形成宇宙暗物质(DM)取决于鳞状质体的主要衰减模式。在任何情况下,结果都为DM提供了开放的大量质量窗口,其相互作用强度是超对称的。

Universe heating in $R^2$-modified gravity is considered. The rates of particle production by the scalaron are calculated for different decay channels. Freezing of massive stable relics with the interaction strength typical for supersymmetry is studied. It is shown that the bounds on masses of supersymmetry-kind particles allowing them to form the cosmological dark matter (DM)depend upon the dominant decay mode of the scalaron. In any case the results presented open much wider mass window for DM with the interaction strength typical for supersymmetry.
