Color breaking baryogenesis

  title={Color breaking baryogenesis},
  author={Michael J. Ramsey-Musolf and Peter T. Winslow and Graham White},
  journal={Physical Review D},
We propose a scenario that generates the observed baryon asymmetry of the Universe through a multi--step phase transition in which SU(3) color symmetry is first broken and then restored. Two mechanisms produce a baryon asymmetry: one is analogous to conventional electroweak baryogenesis; the second involves spontaneous violation of $B-L$ conservation near the phase boundary. The contribution from the electroweak mechanism dominates, while the spontaneous violation of $B-L$ conservation leaves a… Expand

Electroweak baryogenesis above the electroweak scale
A bstractConventional scenarios of electroweak (EW) baryogenesis are strongly constrained by experimental searches for CP violation beyond the SM. We propose an alternative scenario where the EWExpand
Electroweak Baryogenesis with Vector-like Leptons and Scalar Singlets.

Electroweak Baryogenesis from Temperature-Varying Couplings
The fundamental couplings of the Standard Model are known to vary as a function of energy scale through the Renormalisation Group (RG), and have been measured at the electroweak scale at colliders.Expand
Unrestored Electroweak Symmetry.
It is demonstrated that with a simple extension of the standard model it is possible that the EW symmetry was always broken or only temporarily passed through a symmetry-restored phase. Expand

Two-step electroweak baryogenesis
We analyze electroweak baryogenesis during a two-step electroweak symmetry-breaking transition, wherein the baryon asymmetry is generated during the first step and preserved during the second.Expand

The generality of the arguments rules out any mechanism of electroweak baryogenesis that does not make use of a new source of [ital CP] violation and concludes the QCD damping effects reduce the asymmetry produced to a negligible amount. Expand
Electroweak beautygenesis: from b→s CP violation to the cosmic baryon asymmetry.
A new baryogenesis mechanism is proposed--"electroweak beautygenesis"--explicitly showing that these two CP-violating phenomena can be sourced by a common CP phase, in the two-Higgs-doublet model. Expand

Nonlocal electroweak baryogenesis. I. Thin wall regime.
This paper gives an analytic treatment of quantum mechanical reflection in the thin wall regime, in which interactions with the plasma can be neglected as a particle propagates across the wall, and calculates the baryon asymmetry for various parameter ranges and concludes that asymmetries comparable with observations can be generated.
