The Wayne State University particle theory group primarily focuses on investigating the Standard Model (SM) and its potential extensions, exploring connections between theoretical high-energy physics, experimental findings, and cosmological observations. Recently, the team has addressed numerous challenges related to Beyond the SM theories, along with phenomena involving strong, electromagnetic, and weak interactions.
Our current understanding of the Standard Model includes three quark and lepton generations governed by the symmetry groups SU(3) √ó SU(2) √ó U(1), representing strong nuclear, weak nuclear, and electromagnetic forces. These forces are mediated by gluons, W/Z bosons, and photons respectively. Extensive experimental evidence supports this model, particularly in the electroweak sector, which has undergone rigorous testing. Any proposed new physical theory must align with these precise electroweak measurements.
