HECAP Seminar by Chee Sheng Fong - Precision High Scale Baryogenesis
Hybrid
Leonardo Building - Luigi Stasi Seminar Room and via Zoom
Abstract
Baryogenesis should occur before Big Bang Nucleosynthesis to explain the observed cosmic matter-antimatter asymmetry. In order to describe baryogenesis precisely, one needs to describe the evolution of baryon and lepton flavor charges taking into account all the relevant Standard Model processes: Yukawa, electroweak sphaleron and QCD sphaleron interactions. In this talk I will first describe a full-flavor-covariant formalism and then introduce a new quark-flavor-covariant formalism. Then I will discuss application to SO(10) leptogenesis as well as cloistered baryogenesis. This work also results in the first generic baryogenesis public code BOLEH (BaryOn and Lepton charge Evolution in the Hot big bang).
