Search for magnetic monopoles and stable particles with high electric charges in $\sqrt{s}=$13 TeV $pp$ collisions with the ATLAS detector

Abstract

We present a search for magnetic monopoles and high-electric-charge objects using LHC Run 2 $\sqrt{s}=$13 TeV proton$-$proton collisions recorded by the ATLAS detector. A total integrated luminosity of 138 fb${}^{-1}$ was collected by a specialized trigger. No highly ionizing particle candidate was observed. Considering the Drell-Yan and photon-fusion pair production mechanisms as benchmark models, cross-section upper limits are presented for spin-0 and spin-$\frac{1}{2}$ magnetic monopoles of magnetic charge $1g_{\text{D}}$ and $2g_{\text{D}}$ and for high-electric-charge objects of electric charge $20\le |z|\le 100$, for masses between 200 GeV and 4000 GeV. The search improves by approximately a factor of three the previous cross-section limits on the Drell-Yan production of magnetic monopoles and high-electric charge objects. Also, the first ATLAS limits on the photon-fusion pair production mechanism of magnetic monopoles and high-electric-charge objects have been obtained.
