Summary: | A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at √s=8 TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb [superscript −1] are examined. Particles producing anomalously high ionisation, consistent with long-lived massive particles with electric charges from |q|=2e to |q|=6e are searched for. No signal candidate events are observed, and 95 % confidence level cross-section upper limits are interpreted as lower mass limits for a Drell-Yan production model. The mass limits range between 660 and 785 GeV. United States. Dept. of Energy National Science Foundation (U.S.) Brookhaven National Laboratory |
