Late Reheating, Hadronic Jets and Baryogenesis
Takehiko Asaka, Dmitri Grigoriev, Vadim Kuzmin +1
If inflaton couples very weakly to ordinary matter the reheating temperature of the universe can be lower than the electroweak scale. In this letter we show that the late reheating…
Skyrmed Monopoles
D. Yu. Grigoriev, P. M. Sutcliffe, D. H. Tchrakian
We investigate multi-monopole solutions of a modified version of the BPS Yang-Mills-Higgs model in which a term quartic in the covariant derivatives of the Higgs field (a Skyrme te…
Resonant Amplification of Electroweak Baryogenesis at Preheating
J. M. Cornwall, D. Grigoriev, A. Kusenko
We explore viable scenarios for parametric resonant amplification of electroweak (EW) gauge fields and Chern-Simons number during preheating, leading to baryogenesis at the electro…
Electroweak baryogenesis at and after preheating: What's the difference?
Dmitri Grigoriev
Two recent scenarios of preheating-related baryogenesis are compared within the framework of Abelian Higgs model in (1+1) dimensions. It is shown that they shift baryon number in o…
Inflaton-induced sphaleron transitions
Juan Garcia-Bellido, Dmitri Grigoriev
It has recently been proposed that the production of long wavelength Higgs and gauge configurations via parametric resonance at the end of inflation may give rise to the required b…
Non-equilibrium electroweak baryogenesis from preheating after inflation
Juan Garcia-Bellido, Dmitri Grigoriev, Alexander Kusenko +1
We present a novel scenario for baryogenesis in a hybrid inflation model at the electroweak scale, in which the Standard Model Higgs field triggers the end of inflation. One of the…
