The authors' main claim We find that accounting for non-perturbative chirality-breaking transitions due to strong sphalerons reduces the baryonic asymmetry by the factor $(m_t/\pi T)^2$ or $\alpha_W$, provided those processes are in thermal equilibrium.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

  • In the conventional picture of EWBG, one requires a first-order electroweak phase transition, a CP-violating source localized around the bubble wall, and sufficiently slow wall motion so that the generated chiral or charge asymmetry can diffuse into the symmetric phase and be converted into baryon asymmetry by sphaleron processes [ref] (see also [ref] for alternative baryogenesis mechanisms based on the EWPT).
