External leg amputation in conformal invariant three-point function
, 2011 Amputation of external legs is carried out explicitly for the conformal invariant three-point function involving two spinors and one vector field. Our results are consistent with the general result that amputing an external leg in a conformal invariant ...

Conformal correlators of mixed-symmetry tensors [PDF]
, 2014 We generalize the embedding formalism for conformal field theories to the case of general operators with mixed symmetry. The index-free notation encoding symmetric tensors as polynomials in an auxiliary polarization vector is extended to mixed-symmetry ...

Hecke relations in rational conformal field theory [PDF]
Journal of High Energy Physics, 2018 A bstractWe 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 ...

A new characterization of the Euclidean sphere
Anais da Academia Brasileira de CiênciasIn this paper, we obtain a new characterization of the Euclidean sphere as a compact Riemannian manifold with constant scalar curvature carrying a nontrivial conformal vector field which is also conformal Ricci vector field.

Hidden conformal symmetry for vector field on various black hole backgrounds
Journal of High Energy Physics, 2018 Hidden conformal symmetries of scalar field on various black hole backgrounds have been investigated for years, but whether those features hold for other fields are still open questions. Recently, with proper assumptions, Lunin achieved to the separation

Correlation Functions of Dense Polymers and c=-2 Conformal Field Theory [PDF]
, 1998 The model of dense lattice polymers is studied as an example of non-unitary Conformal Field Theory (CFT) with $c=-2$. ``Antisymmetric'' correlation functions of the model are proved to be given by the generalized Kirchhoff theorem.

Entanglement entropy growth in stochastic conformal field theory and the KPZ class [PDF]
Europhysics letters, 2019 We introduce a model of effective conformal quantum field theory in dimension coupled to stochastic noise, where Kardar-Parisi-Zhang (KPZ) class fluctuations can be observed.

Conformal gradient vector fields on Riemannian manifolds with boundary [PDF]
Colloquium Mathematicum, 2018 Let $(M^n,g)$ be an $n$-dimensional compact connected Riemannian manifold with smooth boundary. We show that the presence of a nontrivial conformal gradient vector field on $M$, with an appropriate control on the Ricci curvature makes $M$ to be isometric

On the coupling of vector fields to the Gauss-Bonnet invariant
, 2015 Inflationary models including vector fields have attracted a great deal of attention over the past decade. Such an interest owes to the fact that they might contribute to, or even be fully responsible for, the curvature perturbation imprinted in the CMB.
