Photon-axion conversion cross-sections in a resonant cavity

Abstract

Photon-axion conversions in the resonant cavity with the lowest mode are considered in detail by the Feynman diagram method. The differential cross-sections are presented and numerical evaluations are given. It is shown that there is a resonant conversion for the considered process, in which the conversion cross-sections are much larger than those of the wave guide in the same conditions. Some estimates for experimental conditions are given from our results. © World Scientific Publishing Company.
