| description | The observation of 236 MeV muon neutrinos from kaon-decay-at-rest (KDAR)
originating in the core of the Sun would provide a unique signature of dark
matter annihilation. Since excellent angle and energy reconstruction are
necessary to detect this monoenergetic, directional neutrino flux, DUNE with
its vast volume and reconstruction capabilities, is a promising candidate for a
KDAR neutrino search. In this work, we evaluate the proposed KDAR neutrino
search strategies by realistically modeling both neutrino-nucleus interactions
and the response of DUNE. We find that, although reconstruction of the neutrino
energy and direction is difficult with current techniques in the relevant
energy range, the superb energy resolution, angular resolution, and particle
identification offered by DUNE can still permit great signal/background
discrimination. Moreover, there are non-standard scenarios in which searches at
DUNE for KDAR in the Sun can probe dark matter interactions. |
