We consider scalar field inflation in the Palatini formulation of general relativity. The covariant derivative of the metric is then non-zero. From the effective theory point of view it should couple to other fields. We write down the most general couplings between it and a scalar field that are quadratic in derivatives. We consider both the case when the torsion is determined by the field equations and the case when it is assumed to be zero a priori. We find the metric derivative terms can…

Towards distinguishing variants of non-minimal inflation

We study models of inflation where the scalar field ϕ that drives inflation is coupled non-minimally to gravity via ξ ϕ2 R, or where the gravity sector is enlarged by an R2 term. We consider the

New class of hybrid metric-Palatini scalar-tensor theories of gravity

A class of scalar-tensor theories (STT) including a non-metricity that unifies metric, Palatini and hybrid metric-Palatini gravitational actions with non-minimal interaction is proposed and

Higgs inflation with loop corrections in the Palatini formulation

We compare Higgs inflation in the metric and Palatini formulations of general relativity, with loop corrections treated in a simple approximation. We consider Higgs inflation on the plateau, at a

Higgs inflation at the hilltop

We study inflation with the non-minimally coupled Standard Model Higgs in the case when quantum corrections generate a hilltop in the potential. We consider both the metric and the Palatini

Palatini inflation in models with an R2 term

The Starobinsky model, considered in the framework of the Palatini formalism, in contrast to the metric formulation, does not provide us with a model for inflation, due to the absence of a

Quantum corrections to quartic inflation with a non-minimal coupling: metric vs. Palatini

We study models of quartic inflation where the inflaton field ϕ is coupled non-minimally to gravity, ξ ϕ2 R, and perform a study of quantum corrections in curved space-time at one-loop level. We

Resurrecting Quadratic Inflation with a non-minimal coupling to gravity

We study Quadratic Inflation with the inflaton field ϕ coupled non-minimally to the curvature scalar R, so that the potential during inflation is of the form V∝ m2ϕ2+ξ Rϕ2. We show that with a

Higgs-Palatini Inflation and Unitarity

Cosmological perturbations in the Palatini formulation of modified gravity

Cosmology in extended theories of gravity is considered assuming the Palatini variational principle, for which the metric and connection are independent variables. The field equations are derived to

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
