Bounds on very weakly interacting ultra light scalar and pseudoscalar dark matter from quantum gravity
Abstract In this paper we consider very weakly interacting and ultra light scalar and pseudoscalar dark matter candidates. We show that quantum gravity has important implications for such models and that the masses of the singlet scalar and pseudoscalar fields must be heavier than $$3\times 10^{-3}$...
