Electroweak baryogenesis can be viable in extensions of the SM with new physics near the weak scale. The new states must couple significantly to the SM(-like) Higgs field in order to drive a strongly first-order phase transition. As a result, they often modify the production and decay properties of the Higgs boson. The new physics must also Baryogenesis can occur through the emission of a particle species X with mass M X, whose subsequent decay violates baryon number conservation. If the initial black hole mass is small enough, T 0 = 1/M 0 > M X, the fraction of X particles emitted is given by the equipartition factor f X ∼ g X g∗, (8) where g X denotes the number of degrees of freedom of particle X.

The charges associated with particles and antiparticles are oppo-site, Q X = Q ¯. This striking symmetry would naturally lead us to conclude that the Universe with Baryogenesis is an important channel which can relate particle physics beyond the stan-dard model to data. The challenge for particle physics is to determine how the observed baryon to entropy ratio of n B=s˘10−10 can be generated from symmetric initial conditions (n B = 0) in the very early Universe (here, n B and sdenote the net baryon number and entropy density, respectively). For the baryogenesis requirements are simultaneously satisfied in a single dynamical framework at weak coupling. The hydromagnetic dynamos are one of the key ingredi- ents for the generation of large-scale magnetic fields in tur- bulent environments [1-3] but since the typical scale of the gravitational collapse of the protogalaxy is of the order of In physical cosmology, baryogenesis (also known as baryosynthesis [1] [2]) is the physical process that is hypothesized to have taken place during the early universe to produce baryonic asymmetry, i.e. the imbalance of matter ( baryons) and antimatter (antibaryons) in the observed universe.

Dolgov 1 The Randall Laboratory of Physics, University of Michigan, Ann Arbor, MI 48109-1120 Abstract: A review on the present state of the baryogenesis is given with an emphasis on electroweak baryogenesis. Technical details of the numerous models considered in the literature are not elaborated but unresolved problems of the isssue are considered.
