论文摘要
由于保形异常，考虑到标量衰减的巨大衰变，宇宙学的演变和粒子的产生被认为是标量衰减成一对仪表玻色子的情况。结果表明，在热力化的过程中，可以创建典型的SUSY的耦合强度。如果粒子质量接近$ 10^{12} $ GEV，则这种暗物质将具有适当的宇宙密度。
Cosmological evolution and particle creation in $R^2$-modified gravity are considered for the case of the dominant decay of the scalaron into a pair of gauge bosons due to conformal anomaly. It is shown that in the process of thermalization superheavy dark matter with the coupling strength typical for the GUT SUSY can be created. Such dark matter would have the proper cosmological density if the particle mass is close to $10^{12}$ GeV.
