Leptogenesis in five-dimensional asymptotic grand unification models

open access: yesJournal of High Energy Physics
Asymptotic grand unification models can be constructed in five dimensions compactified on an orbifold. We demonstrate that the parameter space of such models admit solutions that naturally achieve the baryon asymmetry via leptogenesis, these solutions ...

ALP-assisted strong first-order electroweak phase transition and baryogenesis

open access: yesJournal of High Energy Physics
Axion-like particles (ALPs) can be naturally lighter than the electroweak scale. We consider an ALP that couples to the Standard Model Higgs to achieve the strong first-order electroweak phase transition.

Electroweak baryogenesis in 2HDM without EDM cancellation

open access: yesJournal of High Energy Physics
We study two Higgs doublet models with successful electroweak baryogenesis but without cancellations of electric dipole moments (EDMs). For the baryogenesis, additional scalar bosons are favored to couple mainly with the top quark with CP violations ...

Electromagnetic leptogenesis — an EFT-consistent analysis via Wilson coefficients. Part I. Low-scale, non-resonant regime

open access: yesJournal of High Energy Physics
We analyse electromagnetic leptogenesis within the framework of an effective field theory, where the dynamics is governed by the gauge-invariant dipole operator $${\mathcal{O}}_{NB}=\left(\overline{L}{\sigma }^{\mu \nu }N\right)\widetilde{H}{B}_{\mu \nu }

Introduction to Baryo- and Leptogenesis

open access: closedSurveys in High Energy Physics, 2006
Course presented at the ITEP School 2005. These notes aim at an introductory presentation, reviewing in a not-too-technical way the fundamental concepts involved in the baryo/leptogenesis search for the origin of the current excess of matter over antimatter.

Baryo- and Leptogenesis (Outline)

open access: closed, 2005
The cosmological matter-antimatter asymmetry can be understood as consequence of CP violating quark and lepton interactions in the early universe. We review the theoretical foundations and the main baryogenesis mechanisms: electroweak baryogenesis, leptogenesis, Affleck-Dine baryogenesis.
