Add to Calendar 10/12/2018 12:00 pm 10/12/2018 America/Chicago High Energy Phenomenology Seminar: Yoni Kahn (Neutrino factories as a proving ground for thermal dark matter) DESCRIPTION:

The standard WIMP paradigm holds that WIMPs, when discovered, should appear in three modes of observation: direct detection, indirect detection, and high-energy colliders. Below the GeV scale, though, there exist simple and predictive models of dark matter which attains its relic abundance through thermal freeze-out but for which signals are completely absent in all three channels. Here, neutrino factories come to the rescue, as the dark matter may be produced and detected at the same experiment. I will discuss the case study of coannihilating MeV-scale dark matter and show how current and future neutrino experiments can constrain the available parameter space. I will also discuss the recent null results from the MiniBooNE beam-dump mode search, and illustrate how this new data severely narrows the scope of possible new physics explanations for the MiniBooNE excess.
