摘要
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 scala. 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.
