Correlation functions of warped CFT
Journal 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.

Massive Conformal Symmetry and Integrability for Feynman Integrals [PDF]
Physical Review Letters, 2020 In the context of planar holography, integrability plays an important role for solving certain massless quantum field theories such as N=4 SYM theory. In this letter we show that integrability also features in the building blocks of massive quantum field

Conformal symmetry superalgebras [PDF]
Classical 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.

Conformal Symmetry and Unification [PDF]
AIP Conference Proceedings, 1998 The Weyl-Weinberg-Salam model is presented. It is based on the local conformal gauge symmetry. The model identifies the Higgs scalar field in SM with the Penrose-Chernikov-Tagirov scalar field of the conformal theory of gravity.

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

Local conformal symmetry in non-Riemannian geometry and the origin of physical scales. [PDF]
Eur Phys J C Part Fields, 2017 We introduce an extension of the Standard Model and General Relativity built upon the principle of local conformal invariance, which represents a generalization of a previous work by Bars, Steinhardt and Turok. This is naturally realized by adopting as a

Chiral Scale and Conformal Invariance in 2D Quantum Field Theory [PDF]
, 2011 It is well known that a local, unitary Poincare-invariant 2D QFT with a global scaling symmetry and a discrete non-negative spectrum of scaling dimensions necessarily has both a left and a right local conformal symmetry. In this paper we consider a chiral situation beginning with only a left global scaling symmetry and do not assume Lorentz invariance.

Conformal symmetry of QCD in d-dimensions [PDF]
Physics 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.

Hidden conformal symmetry in Randall–Sundrum 2 model: Universal fermion localization by torsion
Physics Letters B, 2017 In this manuscript we describe a hidden conformal symmetry of the second Randall–Sundrum model (RS2). We show how this can be used to localize fermions of both chiralities. The conformal symmetry leaves few free dimensionless constants and constrains the

Fake Conformal Symmetry in Unimodular Gravity [PDF]
Phys. Rev. D 94, 044032 (2016), 2016 We study Weyl symmetry (local conformal symmetry) in unimodular gravity. It is shown that the Noether currents for both Weyl symmetry and global scale symmetry, identically vanish as in the conformally invariant scalar-tensor gravity. We clearly explain why in the class of conformally invariant gravitational theories, the Noether currents vanish by ...
