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

CERN-LHC. 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 and analyzed.No highly ionizing particle candidate was observed. Considering the Drell-Yan and photon-fusion pair production mechanisms as benchmark models, lowest to-date cross-section upper limits are presented for spin-0 and spin-$\frac{1}{2}$ magnetic monopoles of charge 1$g_{D}$ and 2$g_{D}$ and high-electric-charge objects of charge $20\le|z|\le100$, for masses between 200 and 4000 GeV.
