论文摘要
由于在LHC上找不到基于WIMP的经典暗物质特征的证据，因此一些现象学研究提高了通过新的撞机事件拓扑来访问强烈相互互动的黑暗部门的可能性。如果存在黑暗的介子，它们的演变和强环化程序当前几乎没有受到约束。即使原来的腐烂颗粒是黑暗扇形的，它们也可能迅速衰减并导致类似QCD的喷射结构。他们可以表现为半通用的喷气机。或者它们的行为可能是完全探测器稳定的哈子，在这种情况下，最终状态只是缺少的横向动量。在这项贡献中，我们将介绍一项研究，以探索使用JET子结构方法的使用，以在前两种情况下将黑暗扇区与QCD射流区分开，并在IRC-SAFE线性基础上使用可观察物，并讨论LHC在LHC上使用这种方法的方法。
As no evidence for classic WIMP-based signatures of dark matter have been found at the LHC, several phenomenological studies have raised the possibility of accessing a strongly-interacting dark sector through new collider-event topologies. If dark mesons exist, their evolution and hadronization procedure are currently little constrained. They could decay promptly and result in QCD-like jet structures, even though the original decaying particles are dark sector ones; they could behave as semi-visible jets; or they could behave as completely detector-stable hadrons, in which case the final state is just the missing transverse momentum. In this contribution we will introduce a study performed to explore use of jet substructure methods to distinguish dark-sector from QCD jets in the first two scenarios, using observables in a IRC-safe linear basis, and discuss ways forward for this approach to dark-matter at the LHC.
