DOI: 10.1007/jhep04(2019)024
Abstract: A bstractWe investigate the role of leptons in electroweak baryogenesis by studying a relatively simple framework inspired by effective field theory that satisfies all Sakharov conditions. In particular, we study the effectiveness of CP-violating source… read more here.

DOI: 10.1007/jhep08(2019)002
Abstract: Abstract The fundamental couplings of the Standard Model are known to vary as a function of energy scale through the Renormalisation Group (RG), and have been measured at the electroweak scale at colliders. However, the… read more here.

DOI: 10.1007/jhep12(2017)064
Abstract: A bstractWe present the minimal model of electroweak baryogenesis induced by fermions. The model consists of an extension of the Standard Model with one electroweak singlet fermion and one pair of vector like doublet fermions… read more here.

DOI: 10.1098/rsta.2017.0124
Abstract: 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,… read more here.

Adiabatic electroweak baryogenesis driven by an axionlike particle

DOI: 10.1103/physrevd.101.035009
Abstract: An axion-like particle (ALP) offers a new direction in electroweak baryogenesis because the periodic nature enables it to trigger a strong first-order phase transition insensitively to the decay constant $f$. For $f$ much above TeV,… read more here.

Electroweak baryogenesis from light fermion sources: A critical study
Sign Up to like & getrecommendations! Published in 2021 at "Physical Review D"
DOI: 10.1103/physrevd.104.083507
Abstract: Electroweak baryogenesis (EWBG) is sourced by nonstandard CP -violating interactions of the Higgs boson with fermions, usually taken to be the top quark, enhanced by its large Yukawa coupling. Numerous papers have studied EWBG sourced… read more here.
