Electroweak phase transition in the early universe and Baryogenesis
نویسنده
چکیده
In the Standard Model, it is generally accepted that elementary particles get their masses via the Higgs mechanism, which involves a phase transition from the symmetric phase at higher temperatures (close to the Big Bang) to a phase in which the symmetry has been spontaneously broken. One of the outstanding problems in particle physics is to explain the origin of the observed matter-antimatter asymmetry (baryogenesis) which we observe in today’s universe. In this term paper, we look at the phase transition associated with the Higgs mechanism and attempt to explain the above asymmetry using the same. If the phase transition is “first-order” and rapid, it is possible to obtain the observed asymmetry from this model.

Electroweak Phase Transition in the Early Universe ?
Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar M H. There is presumably no true symmetry restoration at high temperature. A first order phase transition occurs, nevertheless, for M H ∼ < 80 GeV whereas the transition to the high temperature regime is described by a crossover for M H ∼ > 80 GeV. Electroweak baryo...
متن کاملElectroweak Baryogenesis with Electroweak Strings
If stable electroweak strings are copiously produced during the electroweak phase transition, they may contribute significantly to the presently observed baryon to entropy ratio of the universe. This analysis establishes the feasibility of implementing an electroweak baryogenesis scenario without a first order phase transition.

Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar M H. There is presumably no true symmetry restoration at high temperature. Nevertheless , a first order phase transition occurs in the standard model for M H ∼ < 70 GeV. For a realistic scalar mass M H ∼ > 70 GeV the transition to the high temperature regime is desc...
متن کاملPrimordial Magnetic Fields and Electroweak Baryogenesis
In this contribution we will shortly review the main mechanism through which primordial magnetic fields may affect the electroweak baryogenesis. It is shown that although strong magnetic fields might enhance the strength of the electroweak phase transition, no benefit is found for baryogenesis once the effect of the field on the sphaleron rate is taken into account. The possible role of hyperma...

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 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 ...
