Sub-GeV Dark Matter Search with MiniBooNE

|Abstract:||There is ample evidence that there exists a gravitationally interacting dark matter, but what it is and its microscopic properties still elude us. Deep underground direct detection experiments have yet to make a definitively claim to detecting WIMP dark matter. This motivates searching for low-mass dark matter, well below the direction detection thresholds, at accelerator facilities. Accelerator sources of dark matter are advantageous because they lead to boosted energies which allows large neutrino detectors to be used. The MiniBooNE detector, which ran for a decade measuring short baseline neutrino oscillations, was used in a dedicated sub-GeV dark matter search in 2014 with Fermilab Booster Neutrino Beam (BNB). For this search, the 8 GeV proton beam was steered off the neutrino production target and into the steel beam stop. Using this beam configuration and the existing and well-understood MiniBooNE detector, the MiniBooNE-darkmatter collaboration searched for low-mass DM in nucleon recoil events. Results from this search as well as future prospects will be presented.|
