论文摘要

我们提出了标准模型的扩展,该模型使用Majorana型费米文化暗物质基于平坦场景,在该场景中,所有标量耦合常数(包括标量质量术语)在Planck量表上消失,即标量势是平坦的。这种情况可以与量子重力的渐近安全范式兼容。我们搜索参数空间,以使模型重现观测到的值,例如希格斯质量,电子山脉真空和深色物质的遗物丰度。我们还研究了Majorana Fermions和核子的自旋非依赖性弹性横截面。结果表明,可以通过暗物质直接检测实验(例如Xenon,Lux和Pandax-ii)测试Majorana Fermions作为暗物质候选者。我们证明,在最小的设置与Planck量表或渐近安全量子重力兼容的最小设置中,扩展模型可能具有很强的可预测性。

We propose an extension of the standard model with Majorana-type fermionic dark matters based on the flatland scenario where all scalar coupling constants, including scalar mass terms, vanish at the Planck scale, i.e. the scalar potential is flat above the Planck scale. This scenario could be compatible with the asymptotic safety paradigm for quantum gravity. We search the parameter space so that the model reproduces the observed values such as the Higgs mass, the electroweak vacuum and the relic abundance of dark matter. We also investigate the spin-independent elastic cross section for the Majorana fermions and a nucleon. It is shown that the Majorana fermions as dark matter candidates could be tested by dark matter direct detection experiments such as XENON, LUX and PandaX-II. We demonstrate that within the minimal setup compatible with the flatland scenario at the Planck scale or asymptotically safe quantum gravity, the extended model could have a strong predictability.
