论文摘要

直接检测暗物质(DM)的敏感性接近所谓的中微子地板,在该地面上很难将DM候选者从背景中微子中脱离。在这项工作中,我们考虑了以下方案:在各种DM直接检测实验中没有报告DM信号,并探讨了对撞机搜索是否可以探测中微子地板下的DM。我们采用了几种简化的模型,其中DM候选夫妇仅通过高维操作员在标准模型中仅用于电动仪表玻色子或Lepton。包括RGE运行效果之后,我们研究了直接检测,间接检测和对撞机搜索的约束。对撞机搜索可以探测中微子地板下方的光DM。尤其是,对于$ \ \barχb_{μν} b^{μν} $的有效相互作用,13 TEV LHC的单孔通道的当前数据已经覆盖了中微子地板的整个参数空间。

The sensitivity of direct detection of dark matter (DM) approaches the so-called neutrino floor below which it is hard to disentangle the DM candidate from the background neutrino. In this work we consider the scenario that no DM signals are reported in various DM direct detection experiments and explore whether the collider searches could probe the DM under the neutrino floor. We adopt several simplified models in which the DM candidate couples only to electroweak gauge bosons or leptons in the standard model through high dimensional operators. After including the RGE running effect we investigate constraints from direct detection, indirect detection and collider searches. The collider search can probe a light DM below neutrino floor. Especially, for the effective interaction of $\barχχB_{μν}B^{μν}$, current data of the mono-photon channel at the 13 TeV LHC has already covered entire parameter space of the neutrino floor.
