Primordial Black Holes from Affleck-Dine Mechanism
  The recent observations of the gravitational waves (GWs) by LIGO-Virgo
collaboration infer the increasing possibility of the primordial black holes
(PBHs). Recently it was pointed out that sufficient PBHs are produced by the
Affleck-Dine mechanism where inhomogeneous baryogenesis takes place due to
change of the Hubble induced mass during and after inflation and forms high
baryon bubbles (HBBs). The produced HBBs have large density contrasts through
the QCD phase transition or stable Q-ball formation, which leads to formation
of the LIGO PBHs. Furthermore, in this model stringent constraints from CMB
$\mu$-distortion and pulsar timing array (PTA) experiments are completely
absent. In this paper, we study the model in full details based on gravity and
gauge mediated supersymmetry breaking scenarios and show that the model can
explain the current GWs events evading observational constraints.
