Event Details

We consider models of light (sub-GeV) dark matter that escape many of the bounds placed by current dark matter searches. Such low mass dark matter candidates, if produced as a thermal relic in the early universe, must be accompanied by light mediators in order to reproduce the dark matter abundance observed in the present-day universe. These light mediators provide new channels for the production and detection of dark matter at fixed-target neutrino experiments and proton beam dumps. The resulting relativistic dark matter beam could be detected through neutral-current-like interactions in detectors sensitive to relativistic neutrinos. We present the results of a dark matter search using the dedicated beam dump run by MiniBooNE, the untapped potential of existing fixed-target neutrino experiments, as well as the projected sensitivity of future experiments such as COHERENT and SHiP
