论文摘要
我们考虑一个黑暗扇区，其中包含一对通过深色光子介体与标准模型结合的几乎变性状态。该设置构成了无弹性暗物质情景的简单实现。最重的黑色状态是长期寿命的，在深色光子和标准模型超荷兰量表玻色子和/或黑暗状态之间的小质量分裂的极限。我们研究了针对搜索长寿命颗粒的拟议LHC实验检测到这种情况的前景，即Faser，Mathusla，codex-B，Al3x，Mapp，Anubis，Anubis和Facet。我们考虑了典型和标量非弹性暗物质的病例。我们表明，这些实验设施可以探测该模型参数空间的未探索区域，我们突出了它们的互补作用。
We consider a dark sector containing a pair of almost degenerate states coupled to the Standard Model through a dark photon mediator. This set-up constitutes a simple realization of the inelastic dark matter scenario. The heaviest dark state is long-lived, in the limit of a small kinetic mixing among the dark photon and the Standard Model hypercharge gauge boson, and/or of a small mass splitting among the dark states. We study the prospects for detection of this scenario at proposed LHC experiments dedicated to search for long-lived particles, namely FASER, MATHUSLA, CODEX-b, AL3X, MAPP, ANUBIS and FACET. We consider both the cases of fermionic and scalar inelastic dark matter. We show that these experimental facilities can probe unexplored regions of the parameter space of this model, and we highlight their complementary roles.
