TLDR
The baryon asymmetry of the Universe which would arise during a first-order electroweak phase transition due to minimal-standard-model processes agrees in sign and magnitude with the observed baryonic excess and for reasonable Kobayashi-Maskawa parameters and mt in the expected range.
Abstract
We calculate the baryon asymmetry of the Universe which would arise during a first-order electroweak phase transition due to minimal-standard-model processes. It agrees in sign and magnitude with the observed baryonic excess, for reasonable Kobayashi-Maskawa parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects. © 1993 The American Physical Society.

Electroweak baryon number non-conservation in the early Universe and in high-energy collisions

TL;DR: In this paper, the anomalous baryon number nonconservation at high temperatures and in high energy collisions is reviewed and applications to electroweak baryogenesis are considered, and the current status of the problem of instanton-like processes at high energies is outlined.

Opening the window for electroweak baryogenesis

TL;DR: In this paper, an analysis of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops, has been performed and it has been shown that the order parameter v(Tc)/Tc can become significantly larger than one, for values of the Higgs and supersymmetric particle masses consistent with the present experimental bounds.
