First search for dyons with the full MoEDAL trapping detector in 13 TeV pp collisions
The MoEDAL trapping detector, consisting of 794 kg of aluminium volumes installed in the forward and lateral regions, was exposed to 4.0 fb-1 of 13 TeV proton-proton collisions at the LHCb interaction point. Evidence for the presence of dyons (particles with electric and magnetic charge) captured in the trapping detector was sought by passing the aluminium volumes comprising the trapping 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 benchmark Drell-Yan production model, we exclude dyons with a magnetic charge ranging up to 6 Dirac charges, and an electric charge reaching as much as 200 times the fundamental electric charge for mass limits in the range 830-3180 GeV.
