Description
In this work we investigate a scenario where the dark matter of the universe is made of light hidden photons. Thanks to a $Z_{2}$ symmetry, the kinetic mixing with the photon is forbidden and the dark photon interacts with the Standard Model only via an axion-like particle, that acts as a messenger. Focusing on signatures involving the ordinary photon, our survey of the phenomenology includes limits from cosmological stability, CMB distortions, astrophysical energy loss, light-shining-through-walls experiments, helioscopes and solar X-ray observations.
