Cosmological evolution in Weyl conformal geometry

  title={Cosmological evolution in Weyl conformal geometry},
  author={Dumitru M. Ghilencea and Tiberiu Harko},
We discuss the cosmological evolution of the Weyl conformal geometry and its associated Weyl quadratic gravity. The Einstein gravity (with a positive cosmological constant) is recovered in the spontaneously broken phase of Weyl gravity; this happens after the Weyl gauge field (ωμ) of scale symmetry, that is part of the Weyl geometry, becomes massive by Stueckelberg mechanism and decouples. This breaking is a natural result of the cosmological evolution of Weyl geometry, in the absence of matter…

Cosmic inflation from broken conformal symmetry
A period of rapidly accelerating expansion is expected in the early Universe implemented by a scalar field slowly rolling down along an asymptotically flat potential preferred by the current data.
Curvature-matter couplings in modified gravity: From Linear Models to conformally invariant theories
In this proceeding, we review modified theories of gravity with a curvature-matter cou- pling between an arbitrary function of the scalar curvature and the Lagrangian density of matter. This explicit
Non-metricity as the origin of mass generation in gauge theories of scale invariance
We discuss gauge theories of scale invariance beyond the Standard Model (SM) and Einstein gravity. We show that the non-metricity of their underlying 4D geometry is at the origin of mass generation
Standard Model in Weyl conformal geometry
We study the Standard Model (SM) in Weyl conformal geometry. This embedding is truly minimal with no new fields beyond the SM spectrum and Weyl geometry. The action inherits a gauged scale symmetry D


Weyl R2 inflation with an emergent Planck scale
Abstract We study inflation in Weyl gravity. The original Weyl quadratic gravity, based on Weyl conformal geometry, is a theory invariant under the Weyl symmetry of gauged scale transformations.
Stueckelberg breaking of Weyl conformal geometry and applications to gravity
Weyl conformal geometry may play a role in early cosmology where effective theory at short distances becomes conformal. Weyl conformal geometry also has a built-in geometric Stueckelberg mechanism:
Cosmological perturbations in conformal gravity
In this paper we continue a study of cosmological perturbations in the conformal gravity theory. In previous work we had obtained a restricted set of solutions to the cosmological fluctuation
On the physical consequences of a Weyl invariant theory of gravity.
In this paper we explore the physical consequences of assuming Weyl invariance of the laws of gravity from the classical standpoint exclusively. Actual Weyl invariance requires to replace the
Broken Weyl Invariance and the Origin of Mass
A massless Weyl-invariant dynamics of a scalar, a Dirac spinor, and electromagnetic fields is formulated in a Weyl space, W4, allowing for conformal rescalings of the metric and of all fields with
Making the Case for Conformal Gravity
We review some recent developments in the conformal gravity theory that has been advanced as a candidate alternative to standard Einstein gravity. As a quantum theory the conformal theory is both
Spontaneous breaking of Weyl quadratic gravity to Einstein action and Higgs potential
A bstractWe consider the (gauged) Weyl gravity action, quadratic in the scalar curvature (R˜$$ \tilde{R} $$) and in the Weyl tensor (C˜μνρσ$$ {\tilde{C}}_{\mu \nu \rho \sigma} $$) of the Weyl
Local conformal symmetry in non-Riemannian geometry and the origin of physical scales
It is argued that physical scales could emerge from a theory with no dimensionful parameters, as a result of the spontaneous breakdown of conformal and electroweak symmetries.
Constraints on the Cosmological Constant due to Scale Invariance
We consider the standard model with local scale invariance. The theory shows exact scale invariance of dimensionally regulated action. We show that massless gauge fields, which may be Abelian or
Cosmological implications of a scale?invariant standard model
We consider a generalization of the standard model of particle physics such that it displays global scale invariance. The gravitational action is also suitably modified to respect this symmetry. This
