Phase Transition in Extended Electroweak Theory
نویسنده
چکیده
The phase transition in the Weinberg-Salam-Glashow (GSW) electroweak theory extended by the majoron and dilaton field is considered. The possibility of the boson condensation in the extreme conditions in the standard electroweak theory is shown. The first order phase transition induces by the radiative corrections (the Coleman-Weinberg potential) in the presence of matter was considered. Due to t-quark mass (∼ 174 GeV) a relatively high Higgs mass (∼ 313 GeV) was obtained. Only a fraction of this mass is connected to the Coleman-Weinberg potential (m CW ∼ 15 GeV). The model produces the first order phase transition for low temperature (T c ∼ 10 GeV).

In this paper, an analytic treatment of electroweak phase transition is proposed within the two-Higgs doublet model. This phase transition occurs in one stage and is strongly first order. Therefore, it can be applied to the electroweak baryogenesis scenario, whereas the standard model cannot provide this condition considering the experimental data. Also, we study CP violation which is one of th...
متن کاملThe Electroweak Phase Transition: a Status Report *
The possibility that the observed cosmological baryon density might be a consequence of non-perturbative dynamics at the electroweak phase transition is one of the most exciting topics at the interface of particle physics and cosmology. However, determining the viability of electroweak baryogenesis in (minimal extensions of) the standard model requires knowledge of the equilibrium behavior of t...
متن کاملSUSY and the Electroweak Phase Transition
We analyze the effective 3 dimensional theory previously constructed for the MSSM and multi-Higgs models to determine the regions of parameter space in which the electroweak phase transition is sufficiently strong for a B + L asymmetry to survive in the low temperature phase. We find that the inclusion of all supersymmetric scalars and all 1-loop corrections has the effect of enhancing the stre...
متن کاملSinglet Higgs Phenomenology and the Electroweak Phase Transition
We study the phenomenology of gauge singlet extensions of the Standard Model scalar sector and their implications for the electroweak phase transition. We determine the conditions on the scalar potential parameters that lead to a strong first order phase transition as needed to produce the observed baryon asymmetry of the universe. We analyze the constraints on the potential parameters derived ...
متن کاملThe Ising model universality of the electroweak theory
Lattice simulations have shown that the first order electroweak phase transition turns into a regular cross-over at a critical Higgs mass mH,c. We have developed a method which enables us to make a detailed investigation of the critical properties of the electroweak theory at mH,c. We find that the transition falls into the 3d Ising universality class. The continuum limit extrapolation of the c...
