Particle Physics at UC San Diego
Particle physics at UCSD conducts research on all aspects of elementary particles and their interactions. Experimental groups work on the CMS experiment at the LHC, the dark matter search experiments (XENON1T/nT, COSINE-100) at deep underground labs, and search for neutrinoless double beta decays (EXO-200/nEXO). Theorists work on many aspects including on phenomenology of the SM, flavor physics, theories beyond the Standard Model, string theory and string-motivated cosmology, collider and dark matter phenomenology, effective field theory, cosmic microwave background, cosmic neutrinos, early universe cosmology etc. Experimental cosmology relevant to particle physics is pursued at UCSD as part of the Astrophysics group.
