摘要

High Energy Physics - Experiment Physics
We present a search for magnetic monopoles and high-electric-charge objects using LHC Run 2√s̅ = 13 TeV proton - proton collisions recorded by the ATLAS detector. A total integrated luminosity of 138 fb ⁻¹was 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- ½magnetic monopoles of magnetic charge1g_(\textrm{D}{}{a})nd2g_(\textrm{D}{}{a})nd for high-electric-charge objects of electric charge20 ≤ |z| ≤ 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.
