Description

A search for long-lived, multi-charged particles has been performed using the ATLAS detector.We have examined data taken during the 2011 LHC running, corresponding to an integrated luminosity of 4.4 fb−1. A search was made for charged particle tracks exhibiting anomalously high ionization consistent with stable massive particles with charges from |q|=2e to |q|=6e. For this search new variables of specific energy loss per path length (dE/dx) have been developed and used in the candidate selection. No excess is observed with respect to the prediction of Standard Model processes. The 95% C.L. cross-section limits are also interpreted as exclusion limits for a simplified Drell-Yan production model.
