Implication of preheating on gravity assisted baryogenesis in -Higgs inflation
Yann Cado, Christoph Englert, Tanmoy Modak +1
We investigate the impact of preheating on baryogenesis in -Higgs inflation. In this scenario, the inclusion of a dimension-six operator ${(R/ Λ^2)} B_{μν} \widetilde{B}^{μν}…

Baryogenesis in -Higgs Inflation: the Gravitational Connection
Yann Cado, Christoph Englert, Tanmoy Modak +1
-Higgs inflation stands out as one of the best-fit models of Planck data. Using a covariant formalism for the inflationary dynamics and the production of helical gauge fields,…

Baryogenesis from Higgs Inflation
Yann Cado, Mariano Quirós
If the inflaton field is coupled to the hypercharge Chern-Simons density , an explosive production of helical gauge fields when inflation ends can trigger baryogenesis a…
