Abstract We propose an experiment for detecting Axion-Like Particles (ALPs) based on the axion-photon interaction in presence of a non-uniform magnetic field. The impact virtual ALPs polarization photons inside cavity is studied and detection scheme proposed. find that normal modes are dispersed differently owing to their coupling background This birefringence, turn, can be observed as phase di...

A bstract We address production of massive axion-like particles by two electromagnetic modes inside a superconducting radio-frequency (SRF) cylindrical cavity. discuss in detail the choice pump and cavity design. numerically compute time-averaged energy density produced axion field for various wide range masses. This allows us to estimate optimal conditions within In addition, we consider photo...

Abstract We investigate a scenario where the dark matter of Universe is made from very light hidden photons transforming under Z 2 -symmetry. In contrast to usual situation, kinetic mixing forbidden by symmetry and photon interacts with Standard Model only via an axion-like particle acting as “messenger”. Focusing on signatures involving ordinary photon, our survey phenomenology includes limits...
