WebJan 22, 2024 · The origin of the matter–antimatter asymmetry of the universe remains unexplained in the Standard Model (SM) of particle physics. The origin of the flavour structure is another major puzzle of the theory. In this article, we report on recent work attempting to link the two themes through the appealing framework of electroweak (EW) … Webelectroweak baryogenesis in the MSSM is very narrow [4]; several parameters must be adjusted to maximize the resulting baryon asymmetry (in particular, one must assume that the wall is very thin, take tanβ<3, and choose the “optimal” bubble wall velocity vw ≈ 0.02), as shown in Fig. 1.
