| Title: | On the wall velocity dependence of electroweak baryogenesis |
| Authors: | Gláuber Carvalho Dorsch Stephan J. Huber Thomas Konstandin |
| Abstract: | We re-evaluate the status of supersonic electroweak baryogenesis using a gener- alized fluid Ansatz for the non-equilibrium distribution functions. Instead of truncating the expansion to first order in momentum, we allow for higher order terms as well, including up to 21 fluctuations. The collision terms are computed analytically at leading-log accuracy. We also point out inconsistencies in the standard treatments of transport in electroweak baryoge- nesis, arguing that one cannot do without specifying an Ansatz for the distribution function. We present the first analysis of baryogenesis using the fluid approximation to higher orders. Our results support the recent findings that baryogenesis may indeed be possible even in the presence of supersonic wall velocities. |
