Searching for Dark Matter and CP Violation

Patrick de Perio
Columbia University

Two outstanding questions in physics are the nature of dark matter and the origin of the matter- antimatter asymmetry in the universe. Astrophysical observations imply the existence of dark matter, an invisible and dominant mass component in the universe, but it has eluded direct detection to date. A measurement of charge-parity (CP) violation in the lepton sector may help explain the observed preponderance of matter over antimatter. I will present new results from the XENON1T dark matter search experiment, consisting of a multi-tonne dual-phase (liquid-gas) xenon time projection chamber, as well as my future plans for the measurement of CP violation by the T2K long-baseline neutrino oscillation experiment and the next-generation large water Cherenkov detector, Hyper-Kamiokande, attempting to answer these two questions.
