MiniBooNE-DM: a dark matter search in a proton beam dump

In a dedicated run where protons from the Fermilab Booster were delivered directly to the steel beam dump of the Booster Neutrino Beamline (BNB), the MiniBooNE detector was used to search for the production of sub-GeV dark matter particles via vector-boson mediators. The signal searched for was the elastic scattering of dark matter particles off nucleons in the detector mineral oil, with neutrinos being an irreducible background. A review of the experiment, its analysis methods, its results and future perspectives are summarized, demonstrating that beam dump experiments provide a novel and promising approach to dark matter searches. This contribution was written for the TAUP 2017 proceedings.

New anti-neutrino cross-section results from MiniBooNE

The first measurements of antineutrino charged-current quasielastic (ν{sup ¯}{sub μ} CCQE, ν{sub µ} + N → µ{sup +} + N{sup ′}) and neutral-current elastic (ν{sup ¯}{sub μ} NCE, ν{sub µ} + N → ν{sub µ} + N) cross sections with 〈E{sub ν{sup ¯}}〉<1 GeV are presented. To maximize the precision of these measurements, many data-driven background measurements were executed, including a first demonstration of charge separation using a non-magnetized detector. Apart from extending our knowledge of antineutrino interactions by probing a new energy range, these measurements constrain signal and background processes for current and future neutrino oscillation experiments and also carry implications for intra-nuclear interactions.
