, 2011 We show that a baryon asymmetry can be generated by dissipative effects during warm inflation via a supersymmetric two-stage mechanism, where the inflaton is coupled to heavy mediator fields that then decay into light species through B- and CP-violating ...

A novel approach to baryogenesis in f(Q,Lm) gravity and its cosmological implications
Nuclear Physics BWe present an examination of the f(Q,Lm) gravity model, in which the functional form f(Q,Lm)=αQn+βLm is postulated and discuss its potential impact on cosmological dynamics and the phenomenon of gravitational baryogenesis.

Simulations of cold electroweak baryogenesis: dependence on the source of CP-violation
Journal of High Energy Physics, 2018 We compute the baryon asymmetry created in a tachyonic electroweak symmetry breaking transition, focusing on the dependence on the source of effective CP-violation. Earlier simulations of Cold Electroweak Baryogenesis have almost exclusively considered a

Affleck-Dine baryogenesis just after inflation [PDF]
, 2015 We propose a new scenario of Affleck-Dine baryogenesis where a flat direction in the MSSM generates B-L asymmetry just after the end of inflation.

Hierarchy from baryogenesis [PDF]
Physical Review D, 2006 We study a recently proposed mechanism to solve the hierarchy problem in the context of the landscape, where the solution of the hierarchy problem is connected to the requirement of having baryons in our universe via Electroweak Baryogenesis. The phase transition is triggered by the fermion condensation of a new gauge sector which becomes strong at a ...

The impact of particle production on gravitational baryogenesis
Physics Letters B, 2016 Baryogenesis driven by curvature effects is investigated by taking into account gravitationally induced particle production in the very early Universe. In our scenario, the baryon asymmetry is generated dynamically during an inflationary epoch powered by

Baryon asymmetry from higher-order matter contributions in gravity
Physics Letters BWe investigate the observed asymmetry between matter and antimatter by incorporating higher-order matter contributions in gravity, specifically analyzing gravitational baryogenesis within the framework of f(R,T2) gravity, where R is the Ricci scalar and ...
