چکیده
Abstract In the conventional metric formulation of gravity, Higgs Inflation model violates unitarity in electroweak vacuum scattering at energy scale Λ ∼ M Pl /ξ, where ξ 10 4 is non-minimal coupling to Ricci scalar. Palatini it commonly believed that /√(ξ), 9 . Here we reconsider violation formulation. We argue there no non-minimally coupled Standard Model energies below Planck scale. this case completely conserves and consistent all up those which quantum gravity becomes important. If true, would imply has a significant advantage over Inflation.

Self-healing of unitarity in Higgs inflation
Article history: Received 21 February 2014 Received in revised form 3 May 2014 Accepted 3 May 2014 Available online 9 May 2014 Editor: M. Trodden We reconsider perturbative unitarity violation in the standard model Higgs inflation model. We show that the Cutkosky cutting rule implied by perturbative unitarity is fulfilled at one-loop. This is a strong indication that unitarity is restored order...
متن کاملInflection-point Higgs Inflation
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 . MP l). In order for a renormalization group (RG) improved effective λφ4 potential to develop an inflection-point, the quartic coupling λ(φ) must exhibit a minimum with an almost vanishing value i...
متن کاملHiggs Dynamics during Inflation
With the discovery of the Higgs boson, and recent measurements from the BICEP2 collaboration indicating a tensor-to-scalar ratio of r = 0.20 −0.05[1], particle physics is now in an interesting position. The most precise measurements of the Higgs boson and top quark masses appear to show that the Electroweak vacuum is unstable under the fluctuations produced by inflation at the energy scale the ...
متن کاملThe Higgs Boson Lineshape and Perturbative Unitarity
We discuss the lineshape of a heavy Higgs boson, and the behaviour well above resonance. Previous studies concluded that the energy-dependent Higgs width should be used in the resonance region, but must not be used well away from it. We derive the full result and show that it smoothly extrapolates these limits. It is extremely simple, and would be straightforward to implement in existing calcul...
متن کاملLittlest Higgs Model and Unitarity Constraints
The Littlest Higgs Model is constrained using the tree-level perturbative arguments, similar to those used to obtain the Higgs mass bound. It is found that demanding that the theory respects perturbative unitarity upto scales of the order of TeV, in turn implies that the scale f , the analog of pion decay constant, is around 4 TeV.
