Experimental Particle Physics
The Experimental Particle Physics group concentrates its efforts on the following activities:
The CMS detector has operated for more than a decade at the Large Hadron Collider (LHC), located near Geneva, Switzerland. The LHC is currently colliding protons at 13 TeV, the highest energy available in the world. At Northeastern we are supporting the end cap muon detector and the electromagnetic detector. We are studying precision measurements of Standard Model processes, and are searching for signatures of new physics, including leptoquarks (exotic particles with properties of both leptons and quarks), dark matter candidates in topologies with Z bosons and invisible decays, and exotic production and decays of Higgs bosons. Professors George Alverson, Emanuela Barberis, Toyoko Orimoto, and Darien Wood focus their research here.
The Pierre Auger Observatory makes use of the one accelerator bigger than the LHC-the one that gives us cosmic rays from intergalactic space. Currently taking data with a fully instrumented detector covering 3000 square kilometers in Argentina, the PAO observes the showers of particles coming from ultra-high-energy cosmic rays. Northeastern is providing the overall software infrastructure for data analysis and is participating in several research projects, including searches for exotic particles produced at extremely high energies.
