The dilaton is a possible inflaton candidate following recent CMB data allowing a non-minimal coupling to the Ricci curvature scalar in the early Universe. In this paper, we introduce an approach that has seldom been used in the literature, namely dilaton inflation with non-local features. More concretely, employing non-local features expressed in J. High Energy Phys. 04 (2007) 029, we study quadratic variations around a de Sitter geometry of an effective action with a non-local dilaton. The… 

R2 inflation to probe non-perturbative quantum gravity

A bstractIt is natural to expect a consistent inflationary model of the very early Universe to be an effective theory of quantum gravity, at least at energies much less than the Planck one. For the

Weyl gauge symmetry and its spontaneous breaking in the standard model and inflation

We discuss the local (gauged) Weyl symmetry and its spontaneous breaking and apply it to model building beyond the Standard Model (SM) and inflation. In models with non-minimal couplings of the

Closed string tachyon driving f(R) cosmology

To study quantum effects on the bulk tachyon dynamics, we replace R with f(R) in the low-energy effective action that couples gravity, the dilaton, and the bulk closed string tachyon of bosonic

Conformal GUT inflation, proton lifetime and non-thermal leptogenesis

In this paper, we generalize Coleman–Weinberg (CW) inflation in grand unified theories (GUTs) such as SU(5)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym}

Superconformal Generalizations of $R^n$--$φ^p$ Interpolating Inflationary Theories

We present the supersymmetric completion of the auxiliary vector modified polynomial $f(R)$ theories that interpolate between the polynomial $f(R)$ theories and chaotic inflation with the power-law

UV completion of the Starobinsky model, tensor-to-scalar ratio, and constraints on nonlocality

In this paper, we build upon the successes of the ultraviolet (UV) completion of the Starobinsky model of inflation. This involves an extension of the Einstein-Hilbert term by an infinite covariant

Generalized ghost-free propagators in nonlocal field theories

In this paper we present an iterative method to generate an infinite class of new nonlocal field theories whose propagators are ghost-free. We first examine the scalar field case and show that the

Effects of Non-locality in Gravity and Quantum Theory

Spacetime—the union of space and time—is both the actor and the stage during physical processes in our fascinating Universe. In Lorentz invariant local theories, the existence of a maximum signalling

Superconformal generalizations of auxiliary vector modified polynomial f(R) theories

We present the supersymmetric completion of the auxiliary vector modified polynomial f(R) theories in their dual scalar-tensor theory formulation that interpolate between the auxiliary vector

Dark matter and Standard Model reheating from conformal GUT inflation

Spontaneous breaking of conformal symmetry has been widely exploited in successful model building of both inflationary cosmology and particle physics phenomenology. Conformal Grand Unified Theory



Occurrence of exact R2 inflation in non-local UV-complete gravity

A bstractThe R + R2, shortly named “R2” (“Starobinsky”) inflationary model, represents a fully consistent example of a one-parameter inflationary scenario. This model has a “graceful exit” from

F-term axion monodromy inflation

A bstractThe continuous shift symmetry of axions is at the heart of several realizations of inflationary models. In particular, axion monodromy inflation aims at achieving super-Planckian field

p-adic inflation

We construct approximate inflationary solutions rolling away from the unstable maximum of p-adic string theory, a nonlocal theory with derivatives of all orders. Novel features include the existence

Soft theorem for the graviton, dilaton and the Kalb-Ramond field in the bosonic string

A bstractWe study the behavior of the scattering amplitudes of the bosonic string involving a soft massless state (graviton, dilaton and Kalb-Ramond antisymmetric tensor) and closed string tachyons

Multi-field conformal cosmological attractors

We describe a broad class of multi-field inflationary models with spontaneously broken conformal invariance. It generalizes the recently discovered class of cosmological attractors with a single

Consistent Higher Derivative Gravitational theories with stable de Sitter and Anti-de Sitter Backgrounds

In this paper we provide the criteria for any generally covariant, parity preserving, and torsion-free theory of gravity to possess a stable de Sitter (dS) or anti-de Sitter (AdS) background. By

α-attractors: Planck, LHC and dark energy

A bstractWe develop four-parameter supergravity models of inflation and dark energy, constrained so that δρρ$$ \frac{\delta \rho }{\rho } $$, ns and the cosmological constant Λ take their known

Inflation in a two 3-form fields scenario

A setting constituted by ℕ 3-form fields, without any direct interaction between them, minimally coupled to gravity, is introduced in this paper as a framework to study the early evolution of the

Towards a formulation of f (R ) supergravity

The supersymmetric completion of $R+R^2$ gravity is known to be equivalent to standard supergravity coupled to two chiral supermultiples with a K\"ahler potential of the no-scale type. The
