论文摘要
众所周知,常规的弗里德曼宇宙学与具有超对称性相互作用强度的稳定颗粒的存在是紧张的,并且比几个TEV都更重。挽救这种颗粒寿命的一种可能的方法可能是对标准宇宙扩张定律的修改,以使这些重型文物的密度大大降低。我们研究了Starrobinsky通货膨胀模型中不同衰减通道的粒子创造。结果表明,在热量超重量的稳定颗粒的过程中,可以以典型的肠道sus耦合强度,以等于观察到的暗物质密度的密度产生。
The conventional Friedmann cosmology is known to be in tension with the existence of stable particles having interaction strength typical for supersymmetry and heavier than several TeV. A possible way to save life of such particles may be a modification of the standard cosmological expansion law in such a way that the density of these heavy relics would be significantly reduced. We study particle creation in the Starobinsky inflationary model for different decay channels of the scalaron. It is shown that in the process of thermalization superheavy stable particles with the coupling strength typical for the GUT SUSY could be created with the density equal to the observed density of dark matter.
