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
Ricci Linear Weyl/Maxwell Mutual Sourcing
We elevate the field theoretical similarities between Maxwell and Weyl vector fields into a full local scale/gauge invariant Weyl/Maxwell mutual sourcing theory. In its preliminary form, and

Higgs-Dilaton Cosmology: an effective field theory approach
The Higgs-dilaton cosmological model is able to describe simultaneously an inflationary expansion in the early Universe and a dark energy dominated stage responsible for the present day acceleration.
From DeWitt initial condition to cosmological quantum entanglement
At the classical level, a linear dilaton action offers an eternal inflation evolution governed by the unified (cosmological constant plus radiation) equation of state &rgr; − 3 P = 4 Λ ?> . At the
Local conformal symmetry in physics and cosmology
We show how to lift a generic non-scale invariant action in Einstein frame into a locally conformally-invariant (or Weyl-invariant) theory and present a new general form for Lagrangians consistent
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
Cosmological perturbations in antigravity
We compute the evolution of cosmological perturbations in a recently proposed Weyl-symmetric theory of two scalar fields with oppositely-signed conformal couplings to Einstein gravity. It is
Weyl gauge-vector and complex dilaton scalar for conformal symmetry and its breaking
Instead of the scalar “dilaton” field that is usually adopted to construct conformally invariant Lagrangians for gravitation, we here propose a hybrid construction, involving both a complex dilaton
