Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 Leptonic CP violating phase δCP in the light neutrino sector and leptogenesis via present matter‐antimatter asymmetry of the Universe entails each other. Probing CP violation in light neutrino oscillation is one of the challenging tasks today. The reactor mixing angleθ13measured in reactor experiments, LBL, and DUNE with high precision in neutrino ...

Supersymmetric baryogenesis [PDF]
Physics Letters B, 1992 Requiring that the baryon number of the universe be generated by anomalous electroweak interactions places strong constraints on the minimal supersymmetric standard model. In particular, the electric dipole moment of the neutron must be greater than $10^{-27}$e-cm. Improvement of the current experimental bound on the neutron's electric dipole moment by

Quintessential baryogenesis [PDF]
Physical Review D, 2003 The simplest explanation for early time acceleration (inflation) and the late time acceleration indicated by recent data is that they have a common origin. We investigate another generic cosmological implication of this possiblity, that the baryon asymmetry of the universe may be generated in such models.

Journal of High Energy Physics, 2012 We propose an alternative mechanism of baryogenesis in which a scalar baryon undergoes a percolating first-order phase transition in the early Universe. The potential barrier that divides the phases contains explicit B and CP violation and the corresponding instanton that mediates decay is therefore asymmetric.

A New Left‐Right Symmetry Model
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 We propose a new L‐R symmetry model where the L‐R symmetry transformation reverses both the L‐R chirality and the local quantum number. We add to the model a global quantum number F whose value is one for fermions (minus one for antifermion) and vanishes for bosons.

Fermi Degenerate Antineutrino Star Model of Dark Energy
Advances in Astronomy, Volume 2020, Issue 1, 2020., 2020 When the Large Hadron Collider resumes operations in 2021, several experiments will directly measure the motion of antihydrogen in free fall for the first time. Our current understanding of the universe is not yet fully prepared for the possibility that antimatter has negative gravitational mass.

, 2008 Baryogenesis, through the decays of heavy bosons, was considered to be one of the major successes of the grand unified theories (GUTs). It was then realized that the sphaleron processes erased any baryon asymmetry from the GUT-baryogenesis at a later ...

Favored Inflationary Models by Scalar Field Condensate Baryogenesis
Galaxies, 2021 We calculate the baryon asymmetry value generated in the Scalar Field Condensate (SCF) baryogenesis model obtained in several inflationary scenarios and different reheating models.
