Abstract
We discuss JUNO sensitivity to the annihilation of MeV dark matter in the galactic halo
via detecting inverse beta decay reactions of electron anti-neutrinos resulting from the
annihilation. We study possible backgrounds to the signature, including the reactor neutrinos,
diffuse supernova neutrino background, charged- and neutral-current interactions of atmospheric
neutrinos, backgrounds from muon-induced fast neutrons and cosmogenic isotopes. A fiducial volume
cut, as well as the pulse shape discrimination and the muon veto are applied to suppress the above
backgrounds. It is shown that JUNO sensitivity to the thermally averaged dark matter annihilation
rate in 10 years of exposure would be significantly better than the present-day best limit set by
Super-Kamiokande and would be comparable to that expected by Hyper-Kamiokande.
