MoEDAL旨在识别高能LHC碰撞中产生的长寿命高电离粒子形式的新物理。它的塑料核轨迹探测器阵列和铝捕获体积提供了两种独立的被动探测技术。我们在这里展示了首次使用捕获技术在13 TeV质子-质子碰撞中寻找磁单极子产生的结果，扩展了之前在LHC运行1期间发表的8 TeV数据。将222 kg的MoEDAL诱捕探测器样品暴露在前方区域，通过超导磁强计寻找感应持续电流进行分析。所有样品中都排除了超过狄拉克电荷一半的磁荷，并首次对13tev pp碰撞中磁单极子的产生进行了限制。这项研究探测的质量范围是以前对撞机实验无法达到的，最高可达狄拉克电荷的五倍。
MoEDAL is designed to identify new physics in the form of long-lived highly ionizing particles produced in high-energy LHC collisions. Its arrays of plastic nuclear-track detectors and aluminium trapping volumes provide two independent passive detection techniques. We present here the results of a first search for magnetic monopole production in 13 TeV proton-proton collisions using the trapping technique, extending a previous publication with 8 TeV data during LHC Run 1. A total of 222 kg of MoEDAL trapping detector samples was exposed in the forward region and analyzed by searching for induced persistent currents after passage through a superconducting magnetometer. Magnetic charges exceeding half the Dirac charge are excluded in all samples and limits are placed for the first time on the production of magnetic monopoles in 13 TeV pp collisions. The search probes mass ranges previously inaccessible to collider experiments for up to five times the Dirac charge.
