Conformal symmetry of QCD in d-dimensions

open access: yesPhysics Letters B, 2019
QCD in d=4−2ϵ space-time dimensions possesses a nontrivial critical point and there are good reasons to expect that this theory restricted to the gauge-invariant subsector is conformally invariant.

Conformal symmetry in quantum gravity

open access: yesEuropean Physical Journal C: Particles and Fields
We study the problem of how to derive conformal symmetry in the framework of quantum gravity. We start with a generic gravitational theory which is invariant under both the general coordinate transformation (GCT) and Weyl transformation (or equivalently,

Disforming to conformal symmetry

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
Abstract We analyse the dynamical properties of disformally transformed theories of gravity. We show that disformal transformation typically introduces novel degrees of freedom, equivalent to the mimetic dark matter, which possesses a Weyl-invariant formulation.

Conformal symmetries of spacetimes [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2002
Summary: We give a unified and global new approach to the study of the conformal structure of the three classical Riemannian spaces as well as of the six relativistic and non-relativistic spacetimes (Minkowskian, de Sitter, anti-de Sitter, and both Newton-Hooke and Galilean).

Conformal Symmetries of Spherical Spacetimes [PDF]

open access: yesInternational Journal of Theoretical Physics, 2008
We investigate the conformal geometry of spherically symmetric spacetimes in general without specifying the form of the matter distribution. The general conformal Killing symmetry is obtained subject to a number of integrability conditions. Previous results relating to static spacetimes are shown to be a special case of our solution.

Hidden conformal symmetry in tree-level graviton scattering

open access: yesJournal of High Energy Physics, 2018
We argue that the scattering of gravitons in ordinary Einstein gravity possesses a hidden conformal symmetry at tree level in any number of dimensions. The presence of this conformal symmetry is indicated by the dilaton soft theorem in string theory, and

Conformal symmetry superalgebras [PDF]

open access: yesClassical and Quantum Gravity, 2013
We show how the rigid conformal supersymmetries associated with a certain class of pseudo-Riemannian spin manifolds define a Lie superalgebra. The even part of this superalgebra contains conformal isometries and constant R-symmetries. The odd part is generated by twistor spinors valued in a particular R-symmetry representation.

Correlation functions of warped CFT

open access: yesJournal of High Energy Physics, 2018
Warped conformal field theory (WCFT) is a two dimensional quantum field theory whose local symmetry algebra consists of a Virasoro algebra and a U(1) Kac-Moody algebra. In this paper, we study correlation functions for primary operators in WCFT.

Conformal symmetry in nuclear structure [PDF]

open access: yesNuclear Physics A, 2021
The purpose of this paper is to introduce the unitary limit as applied in systems of cold atoms into collective states of heavy, even-even nuclei and to identify a related physical example. This is accompanied by the determination of observables of conformal symmetry in nuclear structure.

A new property of the electromagnetic/Yang–Mills-conformal gravity system in spherical symmetry

open access: yesNuclear Physics B, 2019
We find a new property in W2-conformal gravity in spherical symmetry. We demonstrate that the charge of the electromagnetic field varies with respect to the partial scaling symmetry (conformal transformations in subspaces of a spacetime) in the conformal
