Indirect dark matter search with JUNO — •David Blum, Marc Breisch, Jessica Eck, Tobias Heinz, Tobias Lachenmaier, Neha Lad, Axel Müller, Tobias Sterr, and Alexander Tietzsch — Eberhard Karls Universität Tübingen, Physikalisches Institut

The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose 20 kt liquid scintillator neutrino detector currently under construction in southern China. Its main goal is the determination of the neutrino mass ordering by measuring reactor antineutrinos at 53 km baseline. Due to the size and the excellent energy resolution (3% @ 1 MeV) of the detector, JUNO is sensitive to a potential neutrino flux produced by dark matter self-annihilation. 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. Results of a sensitivity study on the dark matter self-annihilation cross section based on a Bayesian analysis are presented in this talk.
