Electroweak Baryogenesis and Higgs Properties [PDF]
, 2012 We explore the connection between the strength of the electroweak phase transition and the properties of the Higgs boson. Our interest is in regions of parameter space that can realize electroweak baryogenesis. We do so in a simplified framework in which

Low-scale baryogenesis from three-body decays [PDF]
Baryogenesis at the TeV scale from CP-violating decays of a massive particle requires some way to avoid the washouts from processes closely related to the existence of CP violation.

Inflationary birefringence and baryogenesis [PDF]
International Journal of Modern Physics D, 2016 A decade ago, the first leptogenesis model based on inflation was proposed, where the complex phase of the inflaton field carries lepton number [S. H. S. Alexander, M. E. Peskin and M. M. Sheikh-Jabbari, Phys. Rev. Lett. 96 (2006) 081301, arXiv:hep-th/0403069 ].

Nambu-Goldstone Affleck-Dine baryogenesis
Journal of High Energy Physics, 2019 The Affleck-Dine mechanism creates the baryon asymmetry of the universe from an angular motion of a complex scalar field. The mechanism is efficient and allows for a low reheating temperature of the universe if the scalar field has a flat potential along

Electroweak Baryogenesis – A Status Report
, 2013 We review the mechanism of electroweak baryogenesis. In the light of recent electric dipole moment measurements and given the results on new physics searches from collider experiments, the status of electroweak baryogenesis is discussed in a variety of ...

Electroweak Phase Transition and Baryogenesis
, 2020 Our universe is apparently matter dominant. Although CP violation is experimentally proven, the full scenario of baryogenesis remains to be unsolved. Matter asymmetry is discussed briefly in this paper and electroweak phase transition (EWPT) is presented

, 2011 We show that a baryon asymmetry can be generated by dissipative effects during warm inflation via a supersymmetric two-stage mechanism, where the inflaton is coupled to heavy mediator fields that then decay into light species through B- and CP-violating ...
