Computation of the winding number diffusion rate due to the cosmological sphaleron.

چکیده
A detailed quantitative analysis of the transition process mediated by a sphaleron type non-Abelian gauge field configuration in curved spacetime is carried out. By examining spectra of the fluctuation operators and applying the zeta function regularization scheme, a closed analytical expression for the transition rate at the one-loop level is derived. This is a unique example of an exact solution for a sphaleron model in 3 + 1 spacetime dimensions.

Finite Energy Instantons in the O(3) Non-linear Sigma Model
We consider winding number transitions in the two dimensional O(3) non-linear sigma model, modified by a suitable conformal symmetry breaking term. We discuss the general properties of the relevant instanton solutions which dominate the transition amplitudes at finite energy, and find the solutions numerically. The Euclidean period of the solution increases with energy, contrary to the behavior...
متن کاملEffect of CP-violation on the sphaleron rate
We calculate the effect of two CP-violating (dimension-eight) operators of the SU(2)-Higgs model on the motion along a particular path from the vacuum to the sphaleron. It turns out that CP-violation may introduce a difference between the sphaleron rate towards larger Chern-Simons number and the rate towards smaller Chern-Simons number. Such a difference induces a non-zero baryon-number without...
متن کاملOn Asymmetric Chern-simons Number Diffusion
At high temperatures the sphaleron rate determines the rate of ChernSimons number changing transitions. Since a change in the Chern-Simons number is accompanied by a (3 times larger) change in the baryon number (in the standard model), the sphaleron rate is an important ingredient of baryogenesis scenarios. The sphaleron rate may be obtained by ignoring the back reaction of the generated baryon...
متن کاملCosmological sphaleron from real tunneling and its fate.
We show that the cosmological sphaleron of the Einstein-Yang-Mills system can be produced from real tunneling geometries. The sphaleron will tend to roll down to the vacuum or pure gauge field configuration, when the universe evolves in the Lorentzian signature region with the sphaleron and the corresponding hypersurface being the initial data for the Yang-Mills field and the universe, respecti...
متن کاملChern-Simons and winding number in a tachyonic electroweak transition
We investigate the development of winding number and Chern-Simons number in a tachyonic transition in the SU(2) Higgs model, motivated by the scenario of cold electroweak baryogenesis. We find that localized configurations with approximately halfinteger winding number, dubbed half-knots, play an important role in this process. When the Chern-Simons number adjusts locally to the winding number, ...
