Gravitational Waves, baryon asymmetry of the universe and electric dipole moment in the CP-violating NMSSM [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2017 In this work, we make the first study of electroweak baryogenesis (EWBG) based on the LHC data in the CP-violating next-to-minimal supersymmetric model (NMSSM) where a strongly first order electroweak phase transition (EWPT) is obtained in the general ...

NEUTRINO MASSES AND THE BARYON ASYMMETRY [PDF]
International Journal of Modern Physics A, 2000 Due to sphaleron processes in the high-temperature symmetric phase of the standard model the cosmological baryon asymmetry is related to neutrino properties. For hierarchical neutrino masses, with B-L broken at the unification scale ΛGUT~1016 GeV, the observed baryon asymmetry nB/s~10-10 can be naturally explained by the decay of heavy Majorana ...

Baryon asymmetry and gravitational waves from pseudoscalar inflation [PDF]
, 2017 In models of inflation driven by an axion-like pseudoscalar field, the inflaton, a, may couple to the standard model hypercharge via a Chern-Simons-type interaction, ℒ ⊃ a/(4Λ) FF̃.

Common origin of nonzero θ13 and baryon asymmetry of the Universe in a TeV scale seesaw model with A4 flavor symmetry [PDF]
Physical Review D, 2017 We study the possibility of generating non-zero reactor mixing angle $\theta_{13}$ and baryon asymmetry of the Universe within the framework of an $A_4$ flavour symmetric model.

Return of the GUT Baryogenesis: as the Source of Helical Hypermagnetic Fields for the Baryon Asymmetry of the Universe [PDF]
, 2018 It has been considered that baryogenesis models without a generation of $B$-$L$ asymmetry such as the GUT baryogenesis do not work since the asymmetry is washed out by the electroweak sphalerons. Here we point out that helical hypermagnetic fields can be

Neutrinoless double beta decay and the baryon asymmetry of the Universe [PDF]
Physical Review D, 2017 We discuss the impact of the observation of neutrinoless double beta decay on the washout of lepton number in the early universe. Neutrinoless double beta decay can be triggered by a large number of mechanisms that can be encoded in terms of standard ...

Primordial baryon asymmetry and sphalerons [PDF]
Nuclear Physics B - Proceedings Supplements, 1995 I show that a cosmological baryon asymmetry generated at the GUT scale is in general safe against washout due to sphalerons and generic $B$- or $L$-violating effects. This result is mainly due to the (almost) conserved number of right-handed electrons at high temperatures $T \gsim {\cal O}(10) $ TeV, but also the mass corrections, in particular the ...

Neutrino CP violation and sign of baryon asymmetry in the minimal seesaw model [PDF]
, 2017 We discuss the correlation between the CP violating Dirac phase of the lepton mixing matrix and the cosmological baryon asymmetry based on the leptogenesis in the minimal seesaw model with two right-handed Majorana neutrinos and the trimaximal mixing for

Evolution of the baryon asymmetry through the electroweak crossover in the presence of a helical magnetic field [PDF]
, 2016 We elaborate upon the model of baryogenesis from decaying magnetic helicity by focusing on the evolution of the baryon number and magnetic field through the Standard Model electroweak crossover. The baryon asymmetry is determined by a competition between
