Abstract (data abstract)
A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2015 and 2016 from proton-proton collisions at $\sqrt{s}$ = 13 TeV are examined using an integrated luminosity of 36.1 fb$^{-1}$. Particles producing anomalously high ionization, consistent with long-lived massive particles with electric charges from $\pm2e$ to $\pm7e$, are searched for. No events are observed, and 95% confidence level cross-section upper limits are interpreted as lower mass limits for a Drell-Yan production model. The multi-charged particle mass limits range between 980 and 1220 GeV.
