Results from the DarkSide-50 Search for Dark Matter
ORAL
Abstract
DarkSide uses a dual-phase Liquid Argon Time Projection Chamber to search for WIMP dark matter. This talk will present the latest result on the search for low mass (<20GeV/c^2) and high mass (>100GeV/c^2) WIMPs from the current experiment, DarkSide-50, running since mid 2015, along with the technical achievements of the experiment. Darkside-50 is a 50-kg-active-mass TPC, filled with argon from an underground source proven to have a concentration of the radioactive 39Ar isotope at least 1000 time less than that found in the atmosphere. The successful results presented here have also paved the way for the extension of the liquid argon dark matter program into the future, such that it will reach the so-called neutrino floor for WIMP masses between 1 GeV/c^2 and hundreds of TeV/c^2 in the coming decade.
