论文摘要
我们研究了LHC与MoEdal探测器一起寻找异国情调的长寿命颗粒的前景，假设在运行结束时预计的30 fb $^{ - 1} $的集成光度为3。Moedal将核轨道探测器组合为远离相互作用的核轨道探测器，对任何高度高度的粒子都敏感，这对任何高度的粒子都具有敏感性。因此，MoEdal能够分别检测出低速$β<0.15 $或$ <0.3 $的单一或双电荷颗粒，并且大于$ {\ cal O}（1）\，{\ rm m}/c $。我们检查了对具有长寿命的各种单打超对称颗粒的敏感性，并检查了具有不同自旋和SU（2）电荷的多种双重持续的长寿命颗粒。我们将前瞻性的MoEdal质量达到了Atlas和CMS的当前限制，这些限制涉及辅助分析假设。对双重收费的费米子的搜索尤其具有竞争力。
We study the prospects of searches for exotic long-lived particles with the MoEDAL detector at the LHC, assuming the integrated luminosity of 30 fb$^{-1}$ that is expected at the end of Run 3. MoEDAL incorporates nuclear track detectors deployed a few metres away from the interaction point, which are sensitive to any highly-ionizing particles. Hence MoEDAL is able to detect singly- or doubly-charged particles with low velocities $β< 0.15$ or $< 0.3$, respectively, and lifetimes larger than ${\cal O}(1) \,{\rm m}/c$. We examine the MoEDAL sensitivity to various singly-charged supersymmetric particles with long lifetimes and to several types of doubly-charged long-lived particles with different spins and SU(2) charges. We compare the prospective MoEDAL mass reaches to current limits from ATLAS and CMS, which involve auxiliary analysis assumptions. MoEDAL searches for doubly-charged fermions are particularly competitive.
