Moduli anomalies and local terms in the operator product expansion

Publikováno v: Journal of High Energy Physics, Vol 2018, Iss 7, Pp 1-23 (2018)

Abstract Local terms in the Operator Product Expansion in Superconformal Theories with extended supersymmetry are identified. Assuming a factorized structure for these terms their contributions are discussed.

Comments on Anomalies in Supersymmetric Theories

Autor: Stefan Theisen, Adam Schwimmer, Sergei M. Kuzenko

Publikováno v: Journal of Physics A: Mathematical and Theoretical

We analyse the relation between anomalies in their manifestly supersymmetric formulation in superspace and their formulation in Wess-Zumino (WZ) gauges. We show that there is a one-to-one correspondence between the solutions of the cohomology problem

Osborn Equation and Irrelevant Operators

Autor: Adam Schwimmer, Stefan Theisen

Publikováno v: Journal of Statistical Mechanics: Theory and Experiment

The structure of the Osborn ("Local Renormalization Group") Equation in the presence of integer dimensional irrelevant operators is studied. We argue that the consistency of the anomalous part of the generating functional requires a beta-function for

Anomalies, conformal manifolds, and spheres

Journal of high energy physics : JHEP

The two-point function of exactly marginal operators leads to a universal contribution to the trace anomaly in even dimensions. We study aspects of this trace anomaly, emphasizing its interpretation as a sigma model, whose target space M is the space

Comments on the Algebraic Properties of Dilaton Actions

Autor: Stefan Theisen, Adam Schwimmer

Publikováno v: Journal of High Energy Physics

We study the relation between the dilaton action and sigma models for the Goldstone bosons of the spontaneous breaking of the conformal group. We argue that the relation requires that the sigma model is diffeomorphism invariant. The origin of the WZW

On Scale and Conformal Invariance in Four Dimensions

Autor: Adam Schwimmer, Stefan Theisen, Zohar Komargodski, Anatoly Dymarsky

Publikováno v: Journal of high energy physics : JHEP
Journal of High Energy Physics

We study the implications of scale invariance in four-dimensional quantum field theories. Imposing unitarity, we find that infinitely many matrix elements vanish in a suitable kinematical configuration. This vanishing is a nontrivial necessary condit

A class of string backgrounds as a semiclassical limit of WZW models

Autor: Adam Schwimmer, Eliezer Rabinovici, David I. Olive

Publikováno v: Physics Letters B. 321:361-364

A class of string backgrounds associated with non semi-simple groups is obtained as a special large level limit of ordinary WZW models. The models have an integer Virasoro central charge and they include the background recently studied by Nappi and W

Spontaneous Breaking of Conformal Invariance and Trace Anomaly Matching

Autor: Adam Schwimmer, Stefan Theisen

Publikováno v: Nuclear Physics B

We argue that when conformal symmetry is spontaneously broken the trace anomalies in the broken and unbroken phases are matched. This puts strong constraints on the various couplings of the dilaton. Using the uniqueness of the effective action for th

Symplectic fusion rings and their metric

Autor: Adam Schwimmer, Doron Gepner

Publikováno v: Nuclear Physics B. 380:147-167

The fusion of fields in a rational conformal field theory gives rise to a ring structure which has a very particular form. All such rings studied so far were shown to arise from some potentials. In this paper the fusion rings of the WZW models based
