Higgs Inflation with four-form couplings

We consider a new inflationary model in which an antisymmetric tensor field A νρσ and its four-form field strength F μνρσ = 4∂ [ μ A νρσ ] are coupled to the scalar sector of the standard model and to the Ricci scalar R . The four-form field induces modifications to the Higgs self-coupling constant,...

Description
Summary:We consider a new inflationary model in which an antisymmetric tensor field A νρσ and its four-form field strength F μνρσ = 4∂ [ μ A νρσ ] are coupled to the scalar sector of the standard model and to the Ricci scalar R . The four-form field induces modifications to the Higgs self-coupling constant, the cosmological constant, and the non-minimal coupling constant, which results in the modification to the inflaton potential. We also show that there is no need for the Higgs-gravity coupling in the presence of four-form gravity interaction, but still can produce the right amount of density perturbation for inflation.
