我们更新了我们以前在LHC运行2中对被困磁单极子的搜索，使用了近六倍的积分光度，并包括用于解释数据的额外模型。由222公斤铝样品组成的MoEDAL正向捕获探测器在LHCb相互作用点附近暴露于2.11 fb −1的13 TeV质子-质子碰撞，并通过寻找通过超导磁力计后的感应持续电流进行分析。磁荷等于狄拉克电荷或以上的排除在所有的样品。在Drell-Yan生产模型中解释了自旋为0，1/2和1的单极子的结果：除了标准的点状耦合，我们还考虑了与动量相关的形状因子的耦合。搜索提供了最好的电流实验室约束磁荷范围从2到5倍狄拉克收费的单极子。
We update our previous search for trapped magnetic monopoles in LHC Run 2 using nearly six times more integrated luminosity and including additional models for the interpretation of the data. The MoEDAL forward trapping detector, comprising 222 kg of aluminium samples, was exposed to 2.11 fb −1 of 13 TeV proton–proton collisions near the LHCb interaction point and analysed by searching for induced persistent currents after passage through a superconducting magnetometer. Magnetic charges equal to the Dirac charge or above are excluded in all samples. The results are interpreted in Drell–Yan production models for monopoles with spins 0, 1/2 and 1: in addition to standard point-like couplings, we also consider couplings with momentum-dependent form factors. The search provides the best current laboratory constraints for monopoles with magnetic charges ranging from two to five times the Dirac charge.
