High energy physics (also known as particle physics) is the study of the subatomicelements of matter and radiation, and their interactions.
At the University of Colorado at Boulder Department of Physics, research in high energy physics is conducted by the High Energy Physics Group. Their research interests include both experimental and theoretical high energy physics.
The experimentalists work in collaboration with such groups as T2K and Compact Muon Solenoid. They conduct research in such places as the European Organization for Nuclear Research (CERN), Fermi National Laboratory (FNAL) and the J-PARC.
The major research areas of the theory group include string theory and quantum gravity, lattice QCD with an emphasis on issues associated with chiral symmetry, and beyond-standard model phenomenology and the origin of fermion masses.
