  • About

    Professor Schwarz is an experimental particle physicist who has performed research in astro-particle physics, collider physics, as well as in accelerator physics and RF engineering. His current research focuses on discovering new physics in high-energy collisions at the Large Hadron Collider and searching for dark matter with direct detection experiments in deep underground laboratories.

    The Large Hadron Collider

    The Large Hadron Collider (LHC) at CERN is the world’s largest (17-mile circumference) and highest-energy (~ 13 TeV) particle collider. Colliding protons at these energies allows scientists to reproduce the conditions of the Universe 1/100th of a billionth of a second after the Big Bang. By studying these collisions, scientists at the LHC hope to answer fundamental questions about the nature of the Universe, such as why do particles have mass, why is there more far more matter than antimatter, and what is the nature of the dark matter.

    At the LHC, Professor Schwarz performs research at the ATLAS experiment, a 7000-ton detector the size of a 7-story building built around the collision point of the beam. His work at ATLAS focuses on searching for evidence of dark matter produced in proton collisions, possible new physics in the Higgs sector, and studying the top quark, which is the heaviest known fundamental particle (more massive than an atom of Silver).

    Searching for Dark Matter

    Over seventy years of observations have led scientists to the conclusion that an invisible (dark) matter permeates the Universe, dominating the matter content so much so that it is responsible for its large-scale structure. Professor Schwarz is currently working on a very sensitive dark matter experiment, DAMIC (Dark Matter in CCDs) which is searching for low mass dark matter using low noise high resistivity CCD’s. The DAMIC experiment is performed 2km underground at SNOLAB in Ontario, Canada.

    Professor Schwarz is the recipient of the 2011 Alvin Tollestrup Award for outstanding postdoctoral research at Fermi National Laboratory from the Universities Research Association.
