Indirect dark matter search with neutrinos in JUNO and THEIA — Lukas Bieger, •David Blum, Marc Breisch, Srijan Delampady, Jessica Eck, Gina Grünauer, Tobias Heinz, Benedict Kaiser, Frieder Kohler, Tobias Lachenmaier, Axel Müller, Tobias Sterr, Alexander Tietzsch, and Jan Züfle — Eberhard Karls Universität, Physikalisches Institut, Tübingen, Germany

Neutrino detectors like the Jiangmen Underground Neutrino Observatory (JUNO) and the prospective neutrino detector THEIA are sensitive to a potential neutrino flux produced by dark matter self-annihilation in the Milky Way. The expected neutrino signals from dark matter self-annihilation and the relevant backgrounds in the energy range from 10 MeV to 100 MeV are investigated for both neutrino detectors. Further background suppression is realized by pulse shape discrimination analysis in JUNO and by studying the ratio between Cherenkov and scintillation light in THEIA. Results of a sensitivity study of JUNO and THEIA on the dark matter self-annihilation cross section are presented in this talk. This work is supported by the Deutsche Forschungsgemeinschaft.
