论文摘要
我们研究了一个环量子校正对纤维化暗物质模型中核子弹性散射的影响。该型号引入了两个新的单元费用和一个单元标量。 Fermions通过Higgs门户与SM颗粒通信。发现参数空间中的某些可行区域从观察到的遗物密度，希格斯隐形衰减宽度和直接检测实验尊重边界时，当考虑到一个环效应时，将大大缩小。这些区域已经居住在中微子地板以下，部分可能是通过当前或将来的直接检测实验来检验的区域。此外，当包括量子校正时，可能会排除某些在树级上可行的区域。
We investigate the effect of one loop quantum corrections on the elastic scattering of dark matter off the nucleon in a fermionic dark matter model. The model introduces two new singlet fermions and a singlet scalar. The fermions communicate with the SM particles through a Higgs portal. It is found that some viable regions in the parameter space respecting the bounds from the observed relic density, the Higgs invisible decay width, and direct detection experiment, will be shrunk significantly when one loop effects are taken into account. The regions already resided below the neutrino floor, partly may come into regions which are testable by the current or future direct detection experiments. In addition, some regions being viable at tree level, may be excluded when quantum corrections are included.
