CP Violation in the Next to Minimal Supersymmetric Standard Model
A. T. Davies, C. D. Froggatt, A. Usai
We consider spontaneous CP violation in the Next to Minimal Supersymmetric Standard Model (NMSSM), without the usual discrete symmetry. CP violation can occur at tree level,…

Spontaneous CP violation and Higgs spectrum in a Next to Minimal Supersymmetric Model
A. T. Davies, C. D. Froggatt, A. Usai
We explore the possibility of spontaneous CP violation within the Next to Minimal Supersymmetric Standard Model. In the most general form of the model, without a discrete sym…

Electroweak Baryogenesis in a Supersymmetric Model
A. T. Davies, C. D. Froggatt, G. Jenkins +1
In the electroweak phase transition there arises the problem of baryon number washout by sphaleron transitions, which can be avoided if the phase transition is strongly enough firs…
