Search for long-lived, multi-charged particles in pp collisions at √s=7 TeV using the ATLAS detector

A search for highly ionising, penetrating particles with electric charges from |q|=2e to 6e is performed using the ATLAS detector at the CERN Large Hadron Collider. Proton-proton collision data taken at s=7 TeV during the 2011 running period, corresponding to an integrated luminosity of 4.4 fb −1 ,...
