We derive general constraints on supersymmetric extension of axion models, in particular paying careful attention to the cosmological effects of saxion. It is found that for every mass range of the saxion from keV to TeV, severe constraints on the energy density of the saxion are imposed. Together with constraints from axino we obtain stringent upper bounds on the reheating temperature.

  1. Decay rate of PQ-ball

    hep-ph 2025-04 conditional novelty 6.0 of 10

    PQ-balls, Q-balls in a spontaneously broken U(1) theory, are metastable in vacuum and decay at a rate proportional to the square of their asymptotic field value.

    hep-ph 2025-10 unverdicted novelty 5.0 of 10

    Spontaneous CP violation is realized in SUSY via an extended spurion formalism in the exact limit and a model with intermediate-scale breaking along pseudo-flat directions stabilized by soft terms and non-perturbative...
