标题： Dark Matter Annihilation Decay at The LHC

摘要： 对撞机实验为揭示暗物质（DM）自相互作用提供了机会。 在本工作中，我们研究在大型强子对撞机（LHC）上生成暗物质束缚态——暗子——的可能性，并讨论暗子的湮灭衰变如何产生力载子。 我们关注两种包含大暗物质自耦合的流行场景：$\lambda$-SUSY模型中的希格斯微子，以及自相互作用暗物质（SIDM）框架。 形成束缚态后，暗物质粒子湮灭为力载子，这些力载子通过即时或位移过程衰变为标准模型粒子。 这为重共振搜索产生了有趣的信号。 我们计算了束缚态的产生率，并研究了现有重共振搜索对未来约束的预期。 显示英文摘要

摘要： Collider experiments provide an opportunity to shed light on dark matter (DM) self-interactions. In this work, we study the possibility of generating DM bound states -- the Darkonium -- at the LHC and discuss how the annihilation decay of the Darkonium produces force carriers. We focus on two popular scenarios that contain large DM self-couplings: the Higgsinos in the $\lambda$-SUSY model, and self-interacting DM (SIDM) framework. After forming bound states, the DM particles annihilate into force mediators, which decay into the standard model particles either through a prompt or displaced process. This generates interesting signals for the heavy resonance search. We calculate the production rate of bound states and study the projected future constraints from the existing heavy resonance searches.
