“…It is well established after the pioneering work of Kirzhnits and Linde [9] that the electroweak SU(2)×U(1) gauge symmetry was unbroken in the early universe. As the universe cooled down to a temperature of order T ∼ 100 GeV, the thermal expectation value of the Higgs field developed a nonzero value, breaking the electroweak symmetry.…”

Electroweak baryogenesis and standard modelCPviolation

We analyze the mechanism of electroweak baryogenesis proposed by Farrar and Shaposhnikov in which the phase of the CKM mixing matrix is the only source of CP violation. This mechanism is based on a phase separation of baryons via the scattering of quasiparticles by the wall of an expanding bubble produced at the electroweak phase transition. In agreement with the recent work of Gavela, Hernández, Orloff and Pène, we conclude that QCD damping effects reduce the asymmetry produced to a negligible amount. We interpret the damping as quantum decoherence. We compute the asymmetry analytically. Our analysis reflects the observation that only a thin, outer layer of the bubble contributes to the coherent scattering of the quasiparticles. The generality of our arguments rules out any mechanism of electroweak baryogenesis that does not make use of a new source of CP violation.

In this talk we review the basic features of the electroweak monopole, and estimate the remnant electroweak monopole density of the standard model in the present universe. We show that, although the electroweak phase transition is of the first order, the monopole production comes from the thermal fluctuations of the Higgs field after the phase transition, not the vacuum bubble collisions during the phase transition. Moreover, most of the monopoles produced initially are annihilated as soon as created, and this annihilation continues very long time, longer than the muon pair annihilation time. As the result the remnant monopole density at present universe becomes very small, of 10 −11 of the critical density, too small to be the dark matter. We discuss the physical implications of our results on the ongoing monopole detection experiments.PACS numbers: 14.80. Hv, Keywords: electroweak monopole, mass of electroweak monopole, cosmological production of electroweak monopole, remnant density of electroweak monopole, seed of large scale structure.

Corrections to the electroweak effective action at finite temperature

We calculate contributions to the finite temperature effective action for the electroweak phase transition (EWPT) at O(g 4 ), i.e. at sec orders in (g 2 T 2 /M 2 ). This requires plasma-mass corrections in the calculation of the effective potential, inclusion of the "lollipop" diagram corrections. We find the EWPT remains too weakly first-order to drive baryogenesis. We calculate some one loop kinetic energy correcti diagrammatic methods; these may be important for saddlepoint configurations such as the bounce or sphaleron.
