论文摘要
在这项工作中，我们旨在为检测LHC的长寿命乘电粒子的前景提供全面的独立模型研究。我们考虑具有旋转0和$ \ frac {1} {2} $的粒子，电荷为范围$ 1 \ le | q/e | \ le 8 $，是$ su（3）_c $下的单线或三重线。这种颗粒可以作为粒子 - 抗粒子对产生，并通过检测器传播，或形成阳性（quarkonium）类似结合的状态。我们考虑在运行3和HL-LHC数据的结束时，可以通过ATLA，CMS和MOEDAL实验提供的新粒子的可能性和估计较低的质量界限。我们发现，Atlas和CM的敏感性通常比Run 3时的Moestal强度强，而它们在HL-LHC中的竞争力可能以$ 3 \ sillsim | Q/e |的竞争力更强。我们考虑的所有类型的长寿命粒子\ Lessim 7 $。
In this work, we aim to provide a comprehensive and largely model independent investigation on prospects to detect long-lived multiply charged particles at the LHC. We consider particles with spin 0 and $\frac{1}{2}$, with electric charges in range $1 \le |Q/e| \le 8$, which are singlet or triplet under $SU(3)_C$. Such particles might be produced as particle-antiparticle pairs and propagate through detectors, or form a positronium(quarkonium)-like bound state. We consider both possibilities and estimate lower mass bounds on new particles, that can be provided by ATLAS, CMS and MoEDAL experiments at the end of Run 3 and HL-LHC data taking periods. We find out that the sensitivities of ATLAS and CMS are generally stronger than those of MoEDAL at Run 3, while they may be competitive at HL-LHC for $3 \lesssim |Q/e| \lesssim 7$ for all types of long-lived particles we consider.
