Baryogenesis from Domain Walls in the Next-to-Minimal Supersymmetric Standard Model

  author={S.A.Abel and P.L.White},
We consider the production of baryon number from collapsing domain walls, and in particular examine the magnitude of CP violation which is required in such schemes. Taking the conventional solution to the domain wall problem in the Next-to-Minimal Supersymmetric Standard Model as an example, we show that the observed baryon assymmetry of the universe may have been generated, even if the initial {\em explicit} CP violation in the Lagrangian were so small ({\em i.e.} gravitational) that it could… 
Aspects of particle cosmology with an emphasis on baryogenesis
Cosmology provides some compelling reasons to expect physics beyond the Standard Model on top of theoretical concerns such as the hierarchy problem and grand unification. In this thesis I explore
Electroweak phase transition in the μνSSM
An extension of the minimal supersymmetric standard model called the μνSSM does not allow a conventional thermal leptogenesis scenario because of the low scale seesaw that it utilizes. Hence, we
The Next-to-Minimal Supersymmetric extension of the Standard Model reviewed
The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) is one of the most favored supersymmetric models. After an introduction to the model, the Higgs sector and the neutralino
The Electroweak Phase Transition: Corralling the Higgs with Colliders & Cosmology
Through this thesis, I investigate the way in which the electroweak phase transition, and therefore the Higgs boson, bridges high energy particle physics and early universe cosmology; moreover, I
