Journal of high energy physics, 2023(11), 1-45.1029-8479http://dx.doi.org/10.1007/JHEP11(2023)112https://hdl.handle.net/20.500.12713/7199We present a search for magnetic monopoles and high-electric-charge objects using LHC Run 2 root s = 13TeV 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-1/2 magnetic monopoles of magnetic charge 1g(D) and 2g(D) and for high-electric-charge objects of electric charge 20 <= vertical bar z vertical bar <= 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 are obtained.eninfo:eu-repo/semantics/openAccessBeyond Standard ModelExoticsHadron-Hadron ScatteringArticle11144WOS:0012573643000012-s2.0-85197421413Q110.1007/JHEP11(2023)112Q1
