Four - point functions in N = 2 superconformal field theories
نویسندگان
چکیده
Four-point correlation functions of hypermultiplet bilinear composites are analysed in N = 2 superconformal field theory using the superconformal Ward identities and the analyticity properties of the composite operator superfields. It is shown that the complete amplitude is determined by a single arbitrary function of the two conformal cross-ratios of the space-time variables.

We study the logarithmic superconformal field theories. Explicitly, the two–point functions of N = 1 logarithmic superconformal field theories (LSCFT) when the Jordan blocks are two (or more) dimensional, and when there are one (or more) Jordan block(s) have been obtained. Using the well known three-point fuctions of N = 1 superconformal field theory (SCFT), three–point functions of N = 1 LSCFT...

متن کاملN = 1 Superconformal Symmetry in Four Dimensional Quantum Field Theory
The implications of N = 1 superconformal symmetry for four dimensional quantum field theories are studied. Superconformal covariant expressions for two and three point functions of quasi-primary superfields of arbitrary spin are found and connected with the operator product expansion. The general formulae are specialised to cases involving a scalar superfield L, which contains global symmetry c...

متن کاملNew Superconformal Field Theories in Four Dimensions and N = 1 Duality
Recently, developments in the understanding of low-energy N = 1 supersymmetric gauge theory have revealed two important phenomena: the appearance of new four-dimensional superconformal field theories and a non-Abelian generalization of electric-magnetic duality at the IR fixed point. This report is a pedagogical introduction to these phenomena. After presenting some necessary background materia...
