Due to their high ionization and unique trajectories in a solenoidal magnetic field, monopoles are expected to leave numerous clusters in the innermost ATLAS pixel detector without associated reconstructed charged-particle tracks or calorimeter activity. This document presents a search for monopole-pair production in ultraperipheral Pb+Pb collisions in the monopole mass range of 20-150 GeV, based on 5.36 TeV data recorded in 2023 by the ATLAS experiment at the Large Hadron Collider. The results are compared with a semiclassical free particle approximation model as well as with a recent search limits obtained by the MoEDAL Collaboration using complementary techniques.</ab> <la>eng</la> <k1>magnetic monopoles; ultraperipheral collisions; lead-lead; HEAVYIONS; </k1> <pb/> <pp/> <yr>2024</yr> <ed/> <ul>http://cds.cern.ch/record/2909809; http://cds.cern.ch/record/2910555/files/ATL-PHYS-PROC-2024-065.pdf; </ul> <no>Imported from Invenio.</no> </reference> </references>
