Abstract: 

Axion (and axion-like-particle), a pseudo-scalar well-motivated in the beyond-the-Standard-Model physics, has a unique two photon vertex, which allows terrestrial experiments to directly look for them from the Sun or as a component of dark matter. Laboratory searches, with both the source and the detection of axion under control, so-called Light-shining-through-walls (LSW), are complementary probes to those direct searches above. We propose a LSW axion search strategy using superconducting radio-frequency (SRF) cavities in the GHz range. SRF cavities have exceptionally high quality factor, which both boost the number of photons stored in the emitter cavity, and enhance the signal power in the receiver cavity.
