Non-minimal Higgs inflation within holographic cosmology

Abstract

We derive a Higgs inflationary model in the context of holographic cosmology, where we consider a universe filled with a Higgs field non-minimally coupled to gravity in a slow-roll regime. The amplitude of density (scalar) perturbations is calculated. In this regard, we show that the background and perturbative parameters characterising the inflationary era are related to the standard one through corrections terms. We found that for the e-fold number N58N\sim 58, the spectral index,nrn_{r}, and the tensor-to-scalar ratio,rr, values are 0.9650.965 and 0.0210.021, respectively, which are in agreement with 2018 Planck observational data. However, as soon as we move from N58N\sim 58, the model is ruled out by the current data.
