Axion dark matter in the post-inflationary Peccei-Quinn symmetry breaking scenario
Andreas Ringwald, Ken'ichi Saikawa
We consider extensions of the Standard Model in which a spontaneously broken global chiral Peccei-Quinn (PQ) symmetry arises as an accidental symmetry of an exact symmetry. F…
Possible resolution of the domain wall problem in the NMSSM
Anupam Mazumdar, Ken'ichi Saikawa, Masahide Yamaguchi +1
We discuss a possibility that the domain wall problem in the next-to-minimal supersymmetric standard model is alleviated without introducing a small explicit breaking term by…
Gravitational waves from domain walls in the next-to-minimal supersymmetric standard model
Kenji Kadota, Masahiro Kawasaki, Ken'ichi Saikawa
The next-to-minimal supersymmetric standard model predicts the formation of domain walls due to the spontaneous breaking of the discrete -symmetry at the electroweak phase tra…
