The Production and Decay of Saxion in the Collision in the Supersymmetric DFSZ Axion Model

The production and decay of the saxion in the collision in the SUSY DFSZ axion model are considered. The production cross-sections depend on the polarization of the initial and final electron beams, the center of mass energy , and the saxion mass . We analyze the decay rate of saxion in the case where the saxion comes to dominate the energy density of the universe before being thermalized for n = 1 and n = 2.
