The weak electroweak phase transition
We present a detailed analysis of the phase transition in the standard model at finite temperature. Using an improved perturbation theory, where plasma masses are determined from a set of one-loop gap equations, we evaluate the effective potential V ef f (ϕ, T) in next-to-leading order, i.e., including terms cubic in the gauge coupling g, the scalar self-coupling λ 1/2 and the top-quark Yukawa ...
متن کاملElectroweak Phase Transition and Baryogenesis
Our universe is apparently matter dominant. Although CP violation is experimentally proven, the full scenario of baryogenesis remains to be unsolved. Matter asymmetry is discussed briefly in this paper and electroweak phase transition (EWPT) is presented as one possible scenario of baryogenesis. Bounds on the Higgs boson mass for such scenario for Standard Model (SM) and Minimal Supersymmetric ...
متن کاملElectroweak Phase Transition and Baryogenesis
I review the status of the strength of the electroweak phase transition, and electroweak baryogenesis in the Minimal Supersymmetric Standard Model (work done with K. Kainulainen and M. Joyce). The emphasis is on new brane-inspired ideas about electroweak baryogenesis, and improvements in the semiclassical treatment of CP violation at a first order electroweak phase transition .
متن کاملElectroweak Baryogenesis and the Phase Transition Dynamics
The baryogenesis is reanalyzed based on the model by A.G.Cohen et al., in which the lepton number, generated by the neutrinos’ scattering from the bubble walls appearing in the development of the electroweak phase transition, is converted to the baryon number excess through the sphaleron transition. A formula obtained in this paper on the lepton number production rate is correct for the both th...
متن کاملSinglets and the Electroweak Phase Transition
Singlet extensions of the Standard Model (SM) allow for a strongly first order electroweak phase transition, because of trilinear terms in the tree-level potential. We present a systematic procedure to study the parameter space of the Next-toMinimal Supersymmetric SM (NMSSM). We find that this model is consistent with electroweak baryogenesis for a wide range of parameters, allowing Higgs masse...
