Abstract:

Abstract: We study a Higgs inflation model with nonminimal coupling term in the context of holographic cosmology in a slow-roll regime. This nonminimal Higgs model is shown to provide very good consistency according to the recent cosmological observation. We found that for the e-fold number N ∼ 58, the spectral index, nr, and the tensor-to-scalar ratio, r, values are 0.965 and 0.021, respectively, which are in agreement with 2018 Planck observational data. However, as soon as we move from N ∼ 58, the model is ruled out by the current data.
