Baryogenesis in the MSSM, nMSSM and NMSSM [PDF]

, 2006
We compare electroweak baryogenesis in the MSSM, nMSSM and NMSSM. We comment on the different sources of CP violation, the phase transition and constraints from EDM measurements.We compare electroweak baryogenesis in the MSSM, nMSSM and NMSSM. We comment

Bino-driven electroweak baryogenesis with highly suppressed electric dipole moments [PDF]

, 2009
It is conventional wisdom that successful electroweak baryogenesis in the Minimal Supersymmetric extension of the Standard Model (MSSM) is in tension with the non-observation of electric dipole moments (EDMs), since the level of CP-violation responsible ...

THE MYSTERY OF ANTIMATTER: WHAT WE KNOW SO FAR

Worldwide Journal of Physics
Antimatter, the mirror counterpart of ordinary matter, continues to intrigue physicists due to its profound implications for cosmology, particle physics, and the fundamental laws of the universe.

Benchmarking a fading window: electroweak baryogenesis in the C2HDM, LHC constraints after Run 2 and prospects for LISA

Journal of High Energy Physics
The origin of the baryon asymmetry of the universe remains one of the most pressing open questions in particle physics and cosmology. Electroweak baryogenesis offers an experimentally testable explanation, requiring new sources of CP violation and a ...

Baryogenesis via leptogenesis in multi-field inflation

European Physical Journal C: Particles and Fields, 2018
In multi-field reheating after modular j-inflation we investigate the conditions under which baryogenesis via non-thermal leptogenesis can be successfully realized.

Electroweak baryogenesis in 2HDM without EDM cancellation

Journal 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 ...

Electroweak Phase Transition and Baryogenesis

, 2020
Our universe is apparently matter dominant. Although CP violation is experimentally proven, the full scenario of baryogenesis remains to be unsolved. Matter asymmetry is discussed briefly in this paper and electroweak phase transition (EWPT) is presented

Baryogenesis and the new cosmology [PDF]

Pramana, 2004
In this talk I begin with a brief review of the status of approaches to understanding the origin of the baryon asymmetry of the universe (BAU). I then describe a recent model unifying three seemingly-distict problems facing particle cosmology: the origin of inflation, the generation of the BAU and the nature of dark energy.
