Description

Cosmological observations indicate that our universe contains dark matter (DM), yet we have no measurements of its microscopic properties. To detect DM with mass below 1GeV, the sensitivity limit of current direct-detection experiments, and one can use accelerators to search for lower mass boosted DM. With high beam intensity and existing neutrino detectors, the Fermilab Booster Neutrino Beamline (BNB) offers this opportunity. One such experiment, MiniBooNE was originally designed to look for electron neutrino appearance signals from muon neutrino beam, and demonstrated high performance to measure neutral current elastic scattering. In 2014, the BNB was operated to send protons directly to the beam dump which suppresses neutrino flux and allows a low-background search for sub-GeV DM. In this talk, we present analysis techniques, predicted sensitivity, and preliminary results from the DM search of MiniBooNE along some ideas for future DM searches using the BNB.
