论文摘要

MOEDAL诱捕探测器由大约800千克铝制组成。它在LHC程序的Run-2期间暴露于LHCB相互作用点的13 TEV Proton-Proton碰撞的6.46 fb^-1。通过通过鱿鱼磁力计的铝制量通过铝体积，通过将铝量传递到捕获探测器中的Dyon（具有电和磁性电荷的颗粒）的证据。乌贼磁力计引起的持续电流会发出捕获的dyon的存在。根据Drell -Yan生产模型，我们排除了磁电荷范围不高5个DIRAC电荷的Dyon，而电荷的最高为200倍，高达790-3130 GEV范围内质量限制的基本电荷。

The MoEDAL trapping detector, consists of approximately 800 kg of aluminium volumes. It was exposed during Run-2 of the LHC program to 6.46 fb^-1 of 13 TeV proton-proton collisions at the LHCb interaction point. Evidence for dyons (particles with electric and magnetic charge) captured in the trapping detector was sought by passing the aluminium volumes comprising the detector through a SQUID magnetometer. The presence of a trapped dyon would be signalled by a persistent current induced in the SQUID magnetometer. On the basis of a Drell-Yan production model, we exclude dyons with a magnetic charge ranging up to 5 Dirac charges, and an electric charge up to 200 times the fundamental electric charge for mass limits in the range 790 - 3130 GeV.
