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.

    "Excluding a thin dark matter disk in the Milky Way with Gaia DR1"

    Presented by Katelin Schutz, UC Berkeley

    If a component of the dark matter has dissipative interactions, it could collapse to form a thin dark disk in our Galaxy coincident with the baryonic disk. It has been suggested that dark disks could explain a variety of observed phenomena, including mass extinction events due to periodic comet impacts. Using the first data release from the Gaia space observatory, I will present the results of a search for a dark disk via its effect on stellar kinematics in the Milky Way. I will discuss our strong new limits that disfavor the presence of a thin dark matter disk and present updated measurements on the total matter density in the solar neighborhood.
