Hadronic axion model in gauge-mediated supersymmetry breaking and the cosmology of the saxion
Recently we proposed a simple hadronic axion model within gauge-mediated supersymmetry breaking. In this paper we discuss various cosmological consequences of the model in great detail. Particular attention is paid to the saxion, a scalar partner of the axion, which is produced as a coherent oscillation in the early universe. …
