摘要: We entertain the exotic possibility that dark matter (DM) decays or annihilations taking place in our galaxy may produce a flux of relativistic very weakly-coupled bosons, axions photons. show there exist several upper bounds for this on Earth assuming generic minimal requirements DM, such as lifetime longer than age Universe an annihilation rate leaves unaffected background evolution during domination. These do not depend identity couplings bosons. then new cannot be large enough to explain recent XENON1T excess, while bosons' Standard Model are consistent with all current experimental and observational constraints. also discuss possible caveat these route excess.
