The measured values of the standard model parameters favors a shallow metastable electroweak vacuum and a deep global minimum. The Higgs relaxation in its present local minimum can only be explained via a large degree of fine-tuning. In this paper, irrespective of new physics beyond the SM, we study the universal effect of gravity on the Higgs dynamics in the early universe. We consider a two-parameter framework in which the Higgs is non-minimally coupled to a higher-curvature gravity. In the… 

Quintessential Inflation with Dynamical Higgs Generation as an Affine Gravity

First, we propose a scale-invariant modified gravity interacting with a neutral scalar inflaton and a Higgs-like S U ( 2 ) × U ( 1 ) iso-doublet scalar field based

Quintessential Inflation with Dynamical Higgs Generation as an Affine Gravity

: First, we propose a scale-invariant modified gravity interacting with a neutral scalar inflaton and a Higgs-like SU ( 2 ) × U ( 1 ) iso-doublet scalar field based on the formalism of non-Riemannian

Stability of the Electroweak Vacuum: Gauge Independence and Advanced Precision.

TLDR
An upper bound on the pole mass of the top quark is derived by requiring that the standard model be stable all the way up to the Planck mass scale and conservatively estimate the theoretical uncertainty.

Higgs boson, renormalization group, and naturalness in cosmology

We consider the renormalization group improvement in the theory of the Standard Model (SM) Higgs boson playing the role of an inflaton with a strong non-minimal coupling to gravity. At the one-loop

Higgs inflation: consistency and generalisations

We analyse the self-consistency of inflation in the Standard Model, where the Higgs field has a large non-minimal coupling to gravity. We determine the domain of energies in which this model

Gravity and the Stability of the Higgs Vacuum.

TLDR
Using a "thin-wall" approximation, a proof of principle is provided that small black holes can act as seeds for vacuum decay, spontaneously nucleating a new Higgs phase centered on the black hole with a lifetime measured in millions of Planck times rather than billions of years.

Higgs mass and vacuum stability in the Standard Model at NNLO

A bstractWe present the first complete next-to-next-to-leading order analysis of the Standard Model Higgs potential. We computed the two-loop QCD and Yukawa corrections to the relation between the

Investigating the near-criticality of the Higgs boson

A bstractWe extract from data the parameters of the Higgs potential, the top Yukawa coupling and the electroweak gauge couplings with full 2-loop NNLO precision, and we extrapolate the SM parameters

Stability, Higgs boson mass, and new physics.

TLDR
It is found that the stability of the electroweak (EW) vacuum strongly depends on new physics interaction at the Planck scale MP, despite of the fact that they are higher-dimensional interactions, apparently suppressed by inverse powers of MP.
