Consistent Irrelevant Deformations of Interacting Conformal Field Theories
I show that under certain conditions it is possible to define consistent irrelevant deformations of interacting conformal field theories. The deformations are finite or have a unique running scale (“quasifinite”). They are made of an infinite number of lagrangian terms and a finite number of independent parameters that renormalize coherently. The coefficients of the irrelevant terms are determi...
متن کاملPerturbative Deformations of Conformal Field Theories Revisited
Recently, there has been renewed interest in the mathematics of the moduli space of conformal field theories, in particular in connection with speculations about elliptic cohomology. The purpose of this paper is to investigate this space by perturbative methods from first principles and from a purely “worldsheet” point of view. It is conjectured that at least at generic points, the moduli space...
متن کاملOn Deformations of Conformal Field Theories
Recently, there has been substantial interest in mathematics in the conjectured moduli space of conformal field theories. The purpose of this paper is to investigate this space by what is known as perturbative methods. First, however, it is important to note that the moduli space itself is not yet well defined. There are different definitions of conformal field theory, for example the Segal app...
متن کاملChiral Deformations of Conformal Field Theories
We study general perturbations of two-dimensional conformal field theories by holomorphic fields. It is shown that the genus one partition function is controlled by a contact term (pre-Lie) algebra given in terms of the operator product expansion. These models have applications to vertex operator algebras, two-dimensional QCD, topological strings, holomorphic anomaly equations and modular prope...
متن کاملConformal Field Theories
All unitary Rational Conformal Field Theories (RCFT) are conjectured to be related to unitary coset Conformal Field Theories, i.e., gauged Wess-ZuminoWitten (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 and their consequences are discussed. Some ...
