Particles can generate primordial inflation of the slow-roll variety, which solves the classical problems of the standard cosmology. The crucial requirement, for this possibility to be feasible, is that the scalar Higgs field is, in a particular way, non-minimally coupled to gravity. A conformal transformation is performed from the Jordan's frame to the Einsten's frame so that a modification on the traditional Higgs potential is found for very large values of the fleld; this allows a high flatness zone and, therefore, primordial inflation of the rodadura lenta variety. The results associated to the spectral index and the tensor to scalar ratio are compared against the most recent observational bounds; from the latter, we conclude that the generation of the large-scale structure is successful in this scenario.

Keywords : Inflation; Higgs boson; non-minimal coupling to gravity.
