Physics analysis

The group is working on a variety of ATLAS physics and performance topics. We study physics processes that rely crucially on the performance of the ATLAS calorimeters and tracking  to measure jets and b-tagging. The current interests of the group are:

• Searches for physics beyond the Standard Model in dijets (W', Z', etc);
• Searches for Susy signatures using leptons;
• Multi-boson production
• ttH

Such topics involve good understanding of QCD jets and b-tagging. As part of this focus we are involved in the optimization of the calorimeter response to jets (being proponents of the method based on cell energy density weighting) and are heavily involved in the ATLAS JetEtMiss Combined Performance group.

In addition, the group investigates physics and detector potential of HL-LHC, HE-LHC and post-LHC colliders.

Much of the above work is anchored on Monte Carlo simulations using computational capabilities of the Argonne Leadership Computing Facility (LCRC/ANL).
