2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/41282I review the status of the strength of the electroweak phase transition, and electroweak baryogenesis in the Minimal Supersymmetric Standard Model (work done with K. Kainulainen and M. Joyce). The emphasis is on new brane-inspired ideas about electroweak baryogenesis, and improvements in the semiclassical treatment of CP violation at a first order electroweak phase transition.7 pages, 3 figures; talk given at COSMO-01, Rovaniemi, Finland, 09/2001High Energy Physics - Phenomenologytext
