State-operator correspondence in celestial conformal field theory

open access: yesJournal of High Energy Physics, 2021
The bulk-to-boundary dictionary for 4D celestial holography is given a new entry defining 2D boundary states living on oriented circles on the celestial sphere.

Algebraic Coset Conformal Field Theories [PDF]

open access: yesCommunications in Mathematical Physics, 2000
All unitary Rational Conformal Field Theories (RCFT) are conjectured to be related to unitary coset Conformal Field Theories, i.e., gauged Wess-Zumino-Witten (WZW) models with compact gauge groups. In this paper we use subfactor theory and ideas of algebraic quantum field theory to approach coset Conformal Field Theories. Two conjectures are formulated

On non-supersymmetric conformal manifolds: field theory and holography

open access: yesJournal of High Energy Physics, 2017
We discuss the constraints that a conformal field theory should enjoy to admit exactly marginal deformations, i.e. to be part of a conformal manifold. In particular, using tools from conformal perturbation theory, we derive a sum rule from which one can ...

Energy Momentum Tensor and Marginal Deformations in Open String Field Theory [PDF]

open access: yes, 2004
Marginal boundary deformations in a two dimensional conformal field theory correspond to a family of classical solutions of the equations of motion of open string field theory.

Note on Weyl versus conformal invariance in field theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
It was argued recently that conformal invariance in flat spacetime implies Weyl invariance in a general curved background for unitary theories and possible anomalies in the Weyl variation of scalar operators are identified.

Non-relativistic conformal field theory in the presence of boundary

open access: yesJournal of High Energy Physics, 2022
We study non-relativistic conformal field theory on a flat space in the presence of a planar boundary. We compute correlation functions of primary operators and obtain the expression for the boundary conformal block.

Conformal Transformations in Metric-Affine Gravity and Ghosts [PDF]

open access: yes, 2012
Conformal transformations play a widespread role in gravity theories in regard to their cosmological and other implications. In the pure metric theory of gravity, conformal transformations change the frame to a new one wherein one obtains a conformal ...

Nonrational Conformal Field Theory [PDF]

open access: yes, 2009
We discuss the problem to develop a mathematical theory of a certain class of nonrational conformal field theories (CFT) which contain the unitary CFT. A variant of the concept of a modular functor is proposed that appears to be suitable for such CFT.

Hecke relations in rational conformal field theory

open access: yesJournal of High Energy Physics, 2018
We define Hecke operators on vector-valued modular forms of the type that appear as characters of rational conformal field theories (RCFTs). These operators extend the previously studied Galois symmetry of the modular representation and fusion algebra of

Correlation functions for chiral primaries in D=6 Supergravity on $AdS_3 \times S^3$ [PDF]

open access: yes, 1999
Six dimensional supergravities on $ADS_3 \times S^3$ present interest due to the role they play in the $AdS/CFT$ correspondence. The correspondence in this case states the equivalence between supergravity on the given background and a still unknown ...
