Dark Matter Search Using the JUNO Neutrino Observation Experiment

Dark matter (DM) is thought to comprise about one-quarter of the universe's energy density, as inferred from a variety of astronomical observations including galaxy cluster collisions. Direct detection via nuclear scattering and optical searches for photons emitted by DM have so far yielded no conclusive signals. Recently, searches using neutrinos — complementary to existing experiments — have attracted attention. In this research, neutrino signals from the annihilation or decay of MeV-scale dark matter are analyzed, demonstrating that the upcoming neutrino experiment JUNO has the capability to detect such dark matter.
