We have seven high energy experimental faculty (Chertok, Conway, Erbacher, Mulhearn, Tripathi, Pantic, and Svoboda). The first five are members of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider at CERN in Geneva Switzerland. CMS is studying proton-proton collisions at 13 TeV, measuring the properties of the Higgs boson and looking for new particles such as those predicted by supersymmetry and other theories beyond the standard model. Tripathi also works on the LUX and LZ experiments, searching for relic dark matter deep underground using biphase xenon detectors. Pantic is a member of the DarkSide collaboration also searching for dark matter using biphase argon detectors. Svoboda's research focuses on neutrino properties, in the SNO+ experiment in Canada, the CAPTAIN project, and the future long-baseline neutrino facility, LBNF.

The experimentalists collaborate closely with the high energy theoretical group (Carlip, Cheng, Gunion, Terning, Luty), who work on particle phenomenology, lattice gauge theory, quantum gravity, theoretical predictions of new phenomena beyond the standard model and cosmology.
