论文摘要
我们考虑使用新数据集探测右手SM Fermions夫妇到新量规组的策略,$ U(1)_ {T3R} $。这种情况为轻型风味尺度提供了自然的解释,也是Sub-GEV暗物质的动机。目前允许有参数空间,但是我们发现可以通过将来的实验探测其中的大部分。特别是,宇宙学和天体物理学观察结果,中微子实验和实验搜索流离失所的可见衰减或无形的衰减都可以发挥作用。尽管如此,还有一个很小的参数空间区域,即使这些即将进行的实验也无法探测。该模型可以解释当前实验室实验允许的参数空间中观察到的2.4-3 $σ$过量事件,但是正在进行的/即将进行的实验室实验将有决定性地探讨这种可能性。
We consider strategies for using new datasets to probe scenarios in which light right-handed SM fermions couple to a new gauge group, $U(1)_{T3R}$. This scenario provides a natural explanation for the light flavor sector scale, and a motivation for sub-GeV dark matter. There is parameter space which is currently allowed, but we find that much of it can be probed with future experiments. In particular, cosmological and astrophysical observations, neutrino experiments and experiments which search for displaced visible decay or invisible decay can all play a role. Still, there is a small region of parameter space which even these upcoming experiments will not be able to probe. This model can explain the observed 2.4-3$σ$ excess of events at the COHERENT experiment in the parameter space allowed by current laboratory experiments, but the ongoing/upcoming laboratory experiments will decisively probe this possibility.
