Title: Inflection-point B - L Higgs inflation

Abstract

Inflection-point inflation is an interesting possibility to realize a successful slow-roll inflation when inflation is driven by a single scalar field with its initial value below the Planck mass (ΦI≲M Pl). In order for a renormalization group (RG) improved effective λΦ 4 potential to develop an inflection-point, the quartic coupling λ(Φ) must exhibit a minimum with an almost vanishing value in its RG evolution, namely λ( ΦI)≃0 and β λ(ΦI)≃0, where β λ is the beta-function of the quartic coupling. As an example, we consider the minimal gauged B-L extended Standard Model at the TeV scale, where we identify the B-L Higgs field as the inflaton field. For a successful inflection-point inflation, which is consistent with the current cosmological observations, the mass ratios among the Z' gauge boson, the right-handed neutrinos and the B-L Higgs boson are fixed. Our scenario can be tested in the future collider experiments such as the High-Luminosity LHC and the SHiP experiments. Finally, in addition, the inflection-point inflation provides a unique prediction for the running of the spectral index α≃-2.7×10 -3($$60\atop{N}$$) 2 (N is the e-folding number), which can be tested in the near future.
