Conformal covariance in 2d conformal and integrable models, in W-algebras and in their supersymmetric extensions

, 1999
Conformal symmetry underlies the mathematical description of various two-dimensional integrable models (e.g. for their Lax representation, Poisson algebra, zero curvature representation,...) or of conformal models (for the anomalous Ward identities ...

Ghost Systems: A Vertex Algebra Point of View

, 1997
Fermionic and bosonic ghost systems are defined each in terms of a single vertex algebra which admits a one-parameter family of conformal structures.

Superconformal Technicolor

, 2011
In supersymmetric theories with a strong conformal sector, soft supersymmetry breaking at the TeV scale naturally gives rise to confinement and chiral symmetry breaking at the same scale.

Ground states of holographic superconductors

, 2009
We investigate the ground states of the Abelian Higgs model in AdS_4 with various choices of parameters, and with no deformations in the ultraviolet other than a chemical potential for the electric charge under the Abelian gauge field.

Partially Composite Higgs in Supersymmetry

, 2012
We propose a framework for natural breaking of electroweak symmetry in supersymmetric models, where elementary Higgs fields are semi-perturbatively coupled to a strong superconformal sector. The Higgs VEVs break conformal symmetry in the strong sector at

Constraints on Higher Spin CFT$_2$

, 2017
We derive constraints on two-dimensional conformal field theories with higher spin symmetry due to unitarity, modular invariance, and causality. We focus on CFTs with $\mathcal{W}_N$ symmetry in the "irrational" regime, where $c>N-1$ and the theories ...

Information Retention by Stringy Black Holes

, 2015
Building upon our previous work on two-dimensional stringy black holes and its extension to spherically-symmetric four-dimensional stringy black holes, we show how the latter retain information. A key r\^ole is played by an infinite-dimensional $W_\infty$

An Infinite Dimensional Symmetry Algebra in String Theory

, 1994
Symmetry transformations of the space-time fields of string theory are generated by certain similarity transformations of the stress-tensor of the associated conformal field theories.

Even spin N = 4 $$ \mathcal{N}=4 $$ holography

Journal of High Energy Physics, 2017
A two-dimensional Sp(2N ) vector model with small N = 4 $$ \mathcal{N}=4 $$ superconformal symmetry is formulated, and its chiral algebra is shown to be freely generated by super-primary fields of even conformal weight.

The matrix-extended W 1 + ∞ $$ {\mathcal{W}}_{1+\infty } $$ algebra

Journal of High Energy Physics, 2019
We construct a quadratic basis of generators of matrix-extended W 1 + ∞ $$ {\mathcal{W}}_{1+\infty } $$ using a generalization of the Miura transformation.
