Conformal Symmetry as a Template for QCD [PDF]

open access: greenContinuous Advances in QCD 2004, 2004
Conformal symmetry is broken in physical QCD; nevertheless, one can use conformal symmetry as a template, systematically correcting for its nonzero $ $ function as well as higher-twist effects. For example, commensurate scale relations which relate QCD observables to each other, such as the generalized Crewther relation, have no renormalization scale ...

Fake Conformal Symmetry in Conformal Cosmological Models [PDF]

open access: yesPhysical Review D, 2015
We examine the local conformal invariance (Weyl invariance) in tensor-scalar theories used in recently proposed conformal cosmological models. We show that the Noether currents associated with Weyl invariance in these theories vanish.

Conformal Symmetry in Field Theory and in Quantum Gravity [PDF]

open access: yesUniverse, 2018
Conformal symmetry always played an important role in field theory (both quantum and classical) and in gravity. We present construction of quantum conformal gravity and discuss its features regarding scattering amplitudes and quantum effective action ...

Implications of nonplanar dual conformal symmetry [PDF]

open access: yesJournal of High Energy Physics, 2018
Recently, Bern et al. observed that a certain class of next-to-planar Feynman integrals possess a bonus symmetry that is closely related to dual conformal symmetry.

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,

Dendrites and conformal symmetry [PDF]

open access: yes, 2014
Progress toward characterization of structural and biophysical properties of neural dendrites together with recent findings emphasizing their role in neural computation, has propelled growing interest in refining existing theoretical models of electrical

Uncovering Conformal Symmetry in the 3D Ising Transition: State-Operator Correspondence from a Quantum Fuzzy Sphere Regularization [PDF]

open access: yesPhysical Review X, 2022
The $3D$ Ising transition, the most celebrated and unsolved critical phenomenon in nature, has long been conjectured to have emergent conformal symmetry, similar to the case of the $2D$ Ising transition. Yet, the emergence of conformal invariance in the $

Exact quantum conformal symmetry, its spontaneous breakdown, and gravitational Weyl anomaly [PDF]

open access: yesPhysical Review D, 2022
The classical Lagrangian of the Standard Model enjoys the symmetry of the full conformal group if the mass of the Higgs boson is put to zero. This is a hint that conformal symmetry may play a fundamental role in the ultimate theory describing Nature. The

Emergent Replica Conformal Symmetry in Non-Hermitian SYK2 Chains [PDF]

open access: yesQuantum, 2021
Recently, the steady states of non-unitary free fermion dynamics are found to exhibit novel critical phases with power-law squared correlations and a logarithmic subsystem entanglement.
