标题： Discovering Inelastic Thermal-Relic Dark Matter at Colliders

摘要： 具有非弹性相互作用的暗物质粒子在标准模型扩展中无处不在，但利用现有策略完全探测它们仍然具有挑战性。 我们提出了一系列在强子和轻子对撞机上强大的搜索方法，这些方法对非弹性暗物质动力学敏感。 在代表性的模型中，这些模型要么包含一个大质量暗光子，要么包含磁偶极相互作用，我们发现，在大约100 MeV到100 GeV的暗物质质量范围内，以及大于百分之一的质量分裂情况下，LHC和BaBar可以对热遗迹暗物质参数空间提供较强的灵敏度；未来在Belle II上的专用单光子触发搜索也可能对低于几GeV质量的热遗迹情景提供灵敏度。 具有较大质量和分裂的热情景大多被排除；较低质量的情况仍然可行，但可能通过其他搜索策略进行探测。 显示英文摘要

摘要： Dark Matter particles with inelastic interactions are ubiquitous in extensions of the Standard Model, yet remain challenging to fully probe with existing strategies. We propose a series of powerful searches at hadron and lepton colliders that are sensitive to inelastic dark matter dynamics. In representative models featuring either a massive dark photon or a magnetic dipole interaction, we find that the LHC and BaBar could offer strong sensitivity to the thermal-relic dark matter parameter space for dark matter masses between ~100 MeV-100 GeV and fractional mass-splittings above the percent level; future searches at Belle II with a dedicated monophoton trigger could also offer sensitivity to thermal-relic scenarios with masses below a few GeV. Thermal scenarios with either larger masses or splittings are largely ruled out; lower masses remain viable yet may be accessible with other search strategies.
