Examining axion-like particles with superconducting radio-frequency cavity
JOURNAL OF HIGH ENERGY PHYSICS(2021)
摘要
bstract We address production of massive axion-like particles by two electromagnetic modes inside a superconducting radio-frequency (SRF) cylindrical cavity. We discuss in detail the choice of pump modes and cavity design. We numerically compute time-averaged energy density of produced axion field for various cavity modes and wide range of axion masses. This allows us to estimate optimal conditions for axion production within a cavity. In addition, we consider photon regeneration process initiated by produced axion field in a screened radio-frequency cavity and derive constraints in parameter space ( g aγγ , m a ) for different choice of pump modes.
