Kinetics of spontaneous baryogenesis in non-stationary background
Published 2016-01-01“…Generation of the cosmological baryon asymmetry in frameworks of spontaneous baryogenesis is studied in detail. It is shown that the relation between baryonic chemical potential and the time derivative of the (pseudo)Goldstone field essentially depends upon the representation chosen for the fermionic fields with non-zero baryonic number (quarks). …”

Spontaneous baryogenesis from axions with generic couplings
Published 2020-08-01“…Abstract Axion-like particles can source the baryon asymmetry of our Universe through spontaneous baryogenesis. Here we clarify that this is a generic outcome for essentially any coupling of an axion-like particle to the Standard Model, requiring only a non-zero velocity of the classical axion field while baryon or lepton number violating interactions are present in thermal bath. …”

Electroweak baryogenesis and electron EDM in the B-LSSM
Published 2020-03-01“…Abstract Electroweak baryogenesis (EWB) and electric dipole moment (EDM) have close relation with the new physics beyond the standard model (SM), because the SM CP-violating (CPV) interactions are not sufficient to provide the baryon asymmetry of the universe by many orders of magnitude, and the theoretical predictions for the EDM of electron ($$d_e$$ de ) in the SM are too tiny to be detected in near future. …”

Electroweak-like baryogenesis with new chiral matter
Published 2021-07-01“…Abstract We propose a framework where a phase transition associated with a gauge symmetry breaking that occurs (not far) above the electroweak scale sets a stage for baryogenesis similar to the electroweak baryogenesis in the Standard Model. …”

Electroweak baryogenesis from temperature-varying couplings
Published 2019-08-01“…We study how such temperature-variance of fundamental gauge couplings can aid the production of a baryon asymmetry in the universe through electroweak baryogenesis. We do so in the context of the Standard Model augmented by higher-dimensional operators up to dimension 6.…”

A mini review on Affleck–Dine baryogenesis
Published 2012-01-01“…We discuss the formation of a condensate along the flat directions in the inflationary era, its post-inflationary evolution leading to baryogenesis and its fate. In some cases the condensate may fragment into non-topological solitons, known as Q -balls, during its evolution. …”

Status of electroweak baryogenesis in minimal composite Higgs
Published 2023-08-01“…Abstract We present an update on the status of electroweak baryogenesis in minimal composite Higgs models. The particularity of this framework is that the electroweak phase transition can proceed simultaneously with the confinement phase transition of the new strong dynamics that produces the composite Higgs. …”

Baryogenesis and gravitational waves in the Zee–Babu model
Published 2022-11-01“…Abstract To explain the matter-antimatter asymmetry in the Zee–Babu (ZB) model, the sphaleron process in the baryogenesis scenario is calculated. It always satisfies the de-coupling condition and the strength of phase transition (S) is always greater than 1 in the presence of triggers other than that in the Standard Model, which are singly ( $$h^{\pm }$$ h ± ) and doubly ( $$k^{\pm \pm }$$ k ± ± ) charged scalar bosons. …”
