The research demonstrates effects of spinless particles coupled to photons, exploring dark matter implications and constraints across different realms.
A pseudoscalar or scalar particle {φ} that couples to two photons but not to leptons, quarks, and nucleons would have effects in most of the experiments searching for axions, since these are based on the a{γ}{γ} coupling. We examine the laboratory, astrophysical, and cosmological constraints on {φ} and study whether it may constitute a substantial part of the dark matter. We also generalize the {φ} interactions to possess SU(2)×{}U(1) gauge invariance, and analyze the phenomenological implications.
