Primordial Magnetic Fields and Electroweak Baryogenesis
نویسنده
چکیده
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 hypermagnetic helicity for the electroweak baryogenesis is shortly discussed. Talk presented at the Third International Conference on Particle Physics and the Early Universe (COSMO-99), Trieste, Italy, 27 Sept 3 Oct, 1999, to appear in the proceedings.

The Sphaleron in a Magnetic Field and Electroweak Baryogenesis
The presence of a primordial magnetic field in the early universe affects the dynamic of the electroweak phase transition enhancing its strength. This effect may enlarge the window for electroweak baryogenesis in the minimal supersymmetric extension of the standard model or even resurrect the electroweak baryogenesis scenario in the standard model. We compute the sphaleron energy in the backgro...
متن کاملPrimordial magnetic fields and CP violation in the sky
It has been argued that electroweak baryogenesis generates a left-handed primordial magnetic field. The helicity density of the primordial magnetic field today is estimated to be ∼ 10nb where nb ∼ 10 −6 /cm is the present cosmological baryon number density. With certain assumptions about the inverse cascade the field strength at recombination is ∼ 10 G on a coherence scale ∼ 10 pc. Here I discu...
متن کاملElectroweak baryogenesis and primordial hypermagnetic fields
The origin of the matter-antimatter asymmetry of the universe remains one of the outstanding questions yet to be answered by modern cosmology and also one of only a handful of problems where the need of a larger number of degrees of freedom than those contained in the standard model (SM) is better illustrated. An appealing scenario for the generation of baryon number is the electroweak phase tr...
متن کاملHelical magnetic fields from sphaleron decay and baryogenesis.
Many models of baryogenesis rely on anomalous particle physics processes to give baryon number violation. By numerically evolving the electroweak equations on a lattice, we show that baryogenesis in these models creates helical cosmic magnetic fields, though the helicity created is smaller than earlier analytical estimates. After a transitory period, electroweak dynamics is found to conserve th...
متن کاملElectroweak Strings, Sphalerons and Magnetic Fields
In this talk I would like to discuss three main topics. First, I will connect electroweak strings and the sphaleron in a more elaborate manner than that described in my paper with George Field 1 and discuss the important issue of the stability of electroweak strings. Secondly, I would like to initiate a discussion of the formation of electroweak strings and their evolution by painting a heurist...
