Electroweak-like baryogenesis with new chiral matter
Journal of High Energy Physics, 2021 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.

Affleck-Dine baryogenesis just after inflation [PDF]
, 2015 We propose a new scenario of Affleck-Dine baryogenesis where a flat direction in the MSSM generates B-L asymmetry just after the end of inflation.

EPJ Web of Conferences, 2018 Among various scenarios of baryon asymmetry of the Universe, electroweak baryogenesis is directly connected with physics of the Higgs sector. We discuss spectra of gravitational waves which are originated by the strongly first order phase transition at ...

Affleck–Dine baryogenesis via mass splitting
Physics Letters B, 2019 We introduce a class of non-supersymmetric models explaining baryogenesis a la Affleck–Dine, which use a decay of two superheavy scalar fields with close masses.

Simulations of cold electroweak baryogenesis: dependence on the source of CP-violation
Journal of High Energy Physics, 2018 We compute the baryon asymmetry created in a tachyonic electroweak symmetry breaking transition, focusing on the dependence on the source of effective CP-violation. Earlier simulations of Cold Electroweak Baryogenesis have almost exclusively considered a

Hidden sector baryogenesis [PDF]
Physics Letters B, 2006 We introduce a novel mechanism for baryogenesis, in which mixed anomalies between the hidden sector and $U(1)_{baryon}$ drive the baryon asymmetry. We demonstrate that this mechanism occurs quite naturally in intersecting-brane constructions of the Standard Model, and show that it solves some of the theoretical difficulties faced in matching ...

Baryogenesis through leptogenesis
, 2000 Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general evolution equations and developing an approximate but sufficiently accurate

Supersymmetric electroweak baryogenesis [PDF]
Journal of High Energy Physics, 2000 We re-examine the generation of the baryon asymmetry in the minimal supersymmetric standard model (MSSM) during the electroweak phase transition. We find that the dominant source for baryogenesis arises from the chargino sector. The CP-violation comes from the complex phase in the mu parameter, which provides CP-odd contributions to the particle ...

Role of cosmological gravitational particle production in baryogenesis
We investigate the generation of the baryon asymmetry within the framework of cosmological gravitational particle production, employing the Bogoliubov approach.
