Sphaleron portal baryogenesis [PDF]

Nontrivial topological vacua of non-Abelian gauge symmetry $SU(3)\times SU(2)_{L}$ of the Standard Model play an important role in baryogenesis. In particular, the baryon (and lepton) number violation from $SU(2)_{L}$ sphaleron is a crucial ingredient ...

Excited lepton baryogenesis

EPJ Web of Conferences, 2017
The excited leptons that share the quantum numbers with the Standard Model leptons but have larger masses are widespread in many promising new physics theories.

STUDIES OF NEUTRINO OSCILLATIONS, NEUTRINO LESS DOUBLE-BETA DECAY, AND THEIR IMPLICATIONS FOR PARTICLE PHYSICS AND COSMOLOGY

Worldwide Journal of Physics
Background: Neutrinos are among the most enigmatic particles in the Standard Model, playing a pivotal role in our understanding of fundamental physics and cosmology. The discovery of neutrino oscillations established that neutrinos possess non-zero mass,

Towards Reviving Electroweak Baryogenesis with a Fourth Generation

Advances in High Energy Physics, 2013
Electroweak baryogenesis is an attractive scenario for explaining the baryon asymmetry of the universe. However, it does not work within the standard model due to two reasons: (1) the strength of CP violation from the Kobayashi-Maskawa mechanism with ...

Big bang baryogenesis [PDF]

, 1994
An overview of baryogenesis in the early Universe is presented. The standard big bang model including big bang nucleosynthesis and inflation is breifly reviewed. Three basic models for baryogenesis will be developed: The ``standard" out-of-equilibrium decay model; the decay of scalar consensates along flat directions in supersymmetric models; and lepto-

Recent Developments in Electroweak baryogenesis [PDF]

, 1998
We discuss some recent developments made in the computation of the baryon asymmetry generated at the electroweak scale. We emphasize that the local number density asymmetries of the particles involved in supersymmetric electroweak baryogenesis must be ...
