论文摘要
暗物质可能包括从未被宇宙等离子体热效的微弱相互作用的巨型颗粒（FIMP）。它们的遗物密度是通过冻结来实现各种质量的，与其他生产机制相比，可以显着扩展可以测试的模型空间。但是，测试Freeze-In所需的微小耦合是具有挑战性的。我们表明，可以通过LHC搜索单喷射事件中的新物理学来探测FIMP，而能量却很大。我们研究了一个$ z'$门户网站模型，其中Gluon歼灭在早期的宇宙中以及今天在Colliders中产生Fimps。 LHC Run 3搜索的搜索可能会发现MEV-TEV范围内的Fimps占用的新物理学。
Dark matter may consist of feebly interacting massive particles (FIMPs) that never thermalized with the cosmic plasma. Their relic density is achieved via freeze-in for a wide range of masses, significantly expanding the model space that can be tested compared to other production mechanisms. However, testing the tiny couplings required by freeze-in is challenging. We show that FIMPs can be probed by LHC searches for new physics in mono-jet events with large missing energy. We study a $Z'$ portal model in which gluon annihilation produces FIMPs in the early universe and today at colliders. Monojet searches by LHC Run 3 might discover new physics accounted for by FIMPs with mass in the MeV-TeV range.
