我们系统地研究了大型强子对撞机上具有轻标量和伪标量候选暗物质的模型以及它们的势信号。首先，我们推导了具有标准模型Higgs介体和具有新的弱尺度介体的模型的宇宙学界限。接下来，我们研究了两个受间接和直接探测过程拓扑启发的过程，它们现在发生在大型强子对撞机探测器内部。我们发现，如果LHC是在介体衰变中产生的，然后与探测器材料散射，在核反冲中产生喷流，那么LHC可以在巨大的质量范围内观察到非常轻的暗物质。
We systematically study models with light scalar and pseudoscalar dark matter candidates and their potential signals at the LHC. First, we derive cosmological bounds on models with the Standard Model Higgs mediator and with a new weak-scale mediator. Next, we study two processes inspired by the indirect and direct detection process topologies, now happening inside the LHC detectors. We find that LHC can observe very light dark matter over a huge mass range if it is produced in mediator decays and then scatters with the detector material to generate jets in the nuclear recoil.
