The Higgs field as an inflaton

The Higgs field of the pure Standard Model can lead to the inflationary expansion of the early Universe if it is non-minimally coupled to gravity. The model predicts Cosmic Microwave Background (CMB)

Eternal Higgs inflation and the cosmological constant problem

We investigate the Higgs potential beyond the Planck scale in the superstring theory, under the assumption that the supersymmetry is broken at the string scale. We identify the Higgs eld as a

I will discuss how the Higgs field of the Standard Model may have played an important role in cosmology, leading to the homogeneity, isotropy and flatness of the Universe; producing the quantum

Asymptotically safe Higgs inflation

We construct a new inflation model in which the standard model Higgs boson couples minimally to gravity and acts as the inflaton. Our construction of Higgs inflation incorporates the standard model

New model of inflation with nonminimal derivative coupling of standard model Higgs boson to gravity.

In this Letter we show that there is a unique nonminimal derivative coupling of the standard model Higgs boson to gravity such that it propagates no more degrees of freedom than general relativity

We consider the extension of the Standard Model (SM) with a light inflaton where both unitarity problem in Higgs inflation and vacuum instability problem are resolved. The linear non-minimal coupling

A simple UV completion for Higgs and Higgs-dilaton inflation

In this work, we present a UV completion for the Higgs and Higgsdilaton inflation which can be reached by adding only one extra R 2 term in the gravity sector. We show that, in this case, the strong

Higgs dark energy

We study the classical dynamics of a non-Abelian Higgs theory coupled to gravity in an isotropic and homogeneous Universe. For non-minimal coupling, this theory leads to a model of cosmic inflation

Light inflaton and Higgs inflation

We consider the extension of the Standard Model (SM) with a light inflaton where the unitarity problem in Higgs inflation is circumvented in the entire field space and the vacuum instability problem



Can gravity make the Higgs particle decouple

The spontaneous symmetry breaking theory of gravity is examined, assuming that the vacuum expectation value of the standard model Higgs is also responsible for the generation of the Planck mass. In

Cosmological Density Perturbations with Modified Gravity

We determine how the usual formula for density perturbations from inflationary cosmology should be modified when the inflaton is coupled to the scalar curvature at the level of the Lagrangian. By

Can gravity play a role at the electroweak scale

A connection is made between a model for strongly interacting vector bosons and the spontaneously broken theory of gravity. The theory contains eectively no Higgs particle, but should have strong

Broken-symmetric theory of gravity

A theory of gravity incorporating the concept of spontaneous symmetry breaking is proposed. It is suggested that the same symmetry-breaking mechanism is responsible for breaking a unified gauge
