چکیده

It is assumed that, in the primordial plasma, at the temperatures above the mass of electron, fermions are in the neutral state being the superposition of particle and antiparticle. There exists neutral proton-electron symmetry. Proton-electron equilibrium is defined by the proton-electron mass difference. At the temperature equal to the mass of electron, pairs of neutral electrons annihilate into photons, and pairs of neutral protons and electrons survive as protons and electrons. Standard scenario of baryogenesis occurs as follows [1]. In the thermodynamically equilibrium primordial plasma, all the particles with m ≤ T exist in equal abundances per spin degree of freedom. This means that, at T > mp, there exist approximately equal abundances of protons p and antiprotons p̄. Excess of baryonic charge arises in the processes of X, Ybosons decays under the following conditions: non-conservation of the baryonic charge and CP-violation. At T < mp, pp̄ annihilate, with the excess of p survives. Let us consider another scenario of baryogenesis. Let us assume that, in the primordial plasma, at T > me, fermions are in the neutral state being the superposition of particle and antiparticle |ψ >= 1 √ 2 (ψ̄ + ψ). (1) Neutral electrons are in the state being the superposition of electron and positron |e >= 1 √ 2 (e− + e). (2) Neutral protons are in the state being the superposition of proton and antiproton |p >= 1 √ 2 (p̄+ p). (3) Let us assume that, at T > me, there exists neutral proton-electron symmetry. For the neutral electron, the sequence of spin transformations ↑↓↑↓↑ transits the particle into itself. Let us identify the cluster of neutral electrons ↑↓↑↓↑ with the neutral proton. The probability of finding such a cluster is given by

Electroweak 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 ...

Curvaton Scenario with Affleck-Dine Baryogenesis

We discuss the curvaton scenario with the Affleck-Dine baryogenesis. In this scenario, non-vanishing baryonic entropy fluctuation may be generated even without primordial fluctuation of the Affleck-Dine field. Too large entropy fluctuation is inconsistent with the observations and hence constraints on the curvaton scenario with the Affleck-Dine baryogenesis are obtained. We calculate the baryon...

Electroweak Baryogenesis with Cosmic Strings? Electroweak Baryogenesis with Cosmic Strings?

I report on a critical analysis of the scenario of electroweak baryoge-nesis mediated by nonsuperconducting cosmic strings. This mechanism relies upon electroweak symmetry restoration in a region around cosmic strings, where sphalerons would be unsuppressed. I discuss the various problems this scenario has to face, presenting a careful computation of the sphaleron rates inside the strings, of t...

Improved Results in Supersymmetric Electroweak Baryogenesis ∗

Electroweak baryogenesis provides a very attractive scenario to explain the origin of the baryon asymmetry. The mechanism of electroweak baryogenesis makes use of the baryon number anomaly and relies on physics that can be tested experimentally. It is today understood that, if the Higgs mass is not larger than 120 GeV, this mechanism may be effective within supersymmetric extensions of the Stan...

Bino-driven electroweak baryogenesis with highly suppressed Electric Dipole Moments

It is conventional wisdom that successful electroweak baryogenesis in the Minimal Supersymmetric extension of the Standard Model (MSSM) is in tension with the non-observation of electric dipole moments (EDMs), since the level of CP-violation responsible for electroweak baryogenesis is believed to generate unavoidably large EDMs. We show that CP-violation in the bino-Higgsino sector of the MSSM ...

نقض CP و گذار فاز الکتروضعیف در مدل دو هیگزی

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...
