 Title: Light spinless particle coupled to photons Author: Massó i Soler, Eduard, 1954-Toldrà Sabaté, Ramon Keywords: AstronomiaAstrofísicaPartícules (Física nuclear)AstronomyAstrophysicsParticles (Nuclear physics)Dark matter (Astronomy)Matèria fosca (Astronomia) Issue Date: 1995 Publisher: The American Physical Society Abstract: A pseudoscalar or scalar particle $\phi$ 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 $a \gamma \gamma$ coupling. We examine the laboratory, astrophysical and cosmological constraints on $\phi$ and study whether it may constitute a substantial part of the dark matter. We also generalize the $\phi$ interactions to possess $SU(2) \times U(1)$ gauge invariance, and analyze the phenomenological implications.
