The Experimental Particle Physics group currently concentrates most of its efforts on the CMS detector.
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.
The DØ detector operated at the Tevatron collider at Fermi National Accelerator Laboratory in Illinois during 2002-2011, where it measured the products of 2 TeV head-on collisions of protons and antiprotons. The large data set at D0 continues to be used for important legacy measurements.
The Pierre Auger Observatory makes use of the one accelerator bigger than either the Tevatron or 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.
