ATLAS search multiply-charged particles First HIP search at the LHC – Very first data (summer 2010) – Standard EM trigger and reco – Interpretation 6e < |q e | < 17e arXiv:1102.0459 (2011) Major source of inefficiency comes from acceptance (punch through) → Model-independent approach: 1-2 pb limits set in well-defined kinematic ranges Sequel: monopole search with 2011 data (next slides) 30
ATLAS monopole search – principle • Data from 2011 (2 fb -1 ) • Standard EM trigger • Special tracking – Count TRT hits in window around EM cluster – Robust against delta-electrons and anomalous bending • Signature: high-threshold TRT hits associated to narrow EM cluster • Interpretation for magnetic monopole with minimum charge (|g| = g D ) – Applying HIP correction in LAr ATLAS-CONF-2012-062 – Simulating monopole dE/dx and trajectory in Geant4 31
