Areas of Research

The High Energy Theory Group has active programs in all areas of particle physics, encompassing Standard Model and beyond, and lattice gauge techniques. Topics of interest include electroweak symmetry breaking and related phenomena, collider physics, precision measurements, physics of flavor, higher order calculations, neutrino interactions, phenomenology of dark sectors, and particle cosmology.

    HET Seminar

    "New physics in rare decays"

    Presented by Julian Heeck, UC Irvine

    2:30 pm, Small Seminar Room, Bldg. 510

    Despite its many successes, the Standard Model of particle physics cannot be the final description of nature at the most fundamental level. Additional elementary particles and interactions are an absolute necessity but have so far evaded our experimental efforts. I will highlight the importance of searches for processes that are forbidden within the Standard Model, as these make for clean signatures of new physics. Important examples are searches for lepton flavor violation and baryon number violation, which will be tested to unprecedented levels in upcoming experiments.

    HET Seminar

    "Phase transitions in the early Universe"

    Presented by Djuna Croon, TRIUMF

    2:30 pm, Small Seminar Room, Bldg. 510

    Thursday, January 30, 2020, 2:30 pm

    In anticipation of the next generation of gravitational wave experiments, I will discuss the opportunities for phenomenological studies of particle physics in the Early Universe. The focus of the talk will be on first order phase transitions in confining gauge theories. Such phase transitions may play an important role in explanations of the strong CP-problem, as well as in models of baryogenesis. I will discuss several such examples and their phenomenology.
