Search for stable mutli-charged particles with the ATLAS experiment

A search for long-lived, multi-charged particles is performed using the ATLAS detector. We examine pp collision-data taken during the 2011 LHC running, corresponding to an integrated luminosity of 4.4 fb−1. A search is made for charged particle tracks exhibiting anomalously high ionization consisten...
