Search for heavy long-lived multi-charged particles in the full LHC Run 2 pp collision data at √s = 13 TeV using the ATLAS detector Aad, Georges Aguilar Saavedra, Juan Antonio Rodríguez Chala, Mikael Atlas Collaboration, / A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2015–2018 at √s = 13 TeV from pp collisions corresponding to an integrated luminosity of 139 fb−1 are examined. Particles producing anomalously high ionization, consistent with long-lived spin-½ massive particles with electric charges from |q| = 2e to |q| = 7e are searched for. No statistically significant evidence of such particles is observed, and 95% confidence level cross-section upper limits are calculated and interpreted as the lower mass limits for a Drell–Yan plus photon-fusion production mode. The least stringent limit, 1060 GeV, is obtained for |q| = 2e particles, and the most stringent one, 1600 GeV, is for |q| = 6e particles. 2024-05-13T09:40:42Z 2024-05-13T09:40:42Z 2023-11-10 journal article Aad, Georges, et al.
