Extremal correlators in four-dimensional SCFT
نویسنده
چکیده
It is shown that certain extremal correlators in four-dimensional N = 2 superconformal field theories (including N = 4 super-Yang-Mills as a special case) have a free-field functional form. It is further argued that the coupling constant dependence receives no correction beyond the lowest order. These results hold for any finite value of Nc. 1 UMR 5108 associée à l’Université de Savoie

Extremal and next-to-extremal n-point correlators in four-dimensional SCFT
It is shown that certain extremal and next-to-extremal n-point correlators in four-dimensional N = 2 superconformal field theories are free. These results hold for any gauge group. 1 UMR 5108 associée à l’Université de Savoie

A discussion of the AdS/CFT correspondence in IIB is given in a superspace context. The main emphasis is on the properties of SCFT correlators on the boundary which are studied using harmonic superspace techniques. These techniques provide the easiest way of implementing the superconformal Ward identities. The Ward identities, together with an-alyticity, can be used to give a compelling argumen...
متن کاملNon-renormalisation of extremal correlators in N=4 SYM theory
We show that extremal correlators of chiral primary operators in N=4 supersymmetric Yang–Mills theory with SU(N) gauge group are neither renormalised at first (g2) order in perturbation theory nor receive contribution from any instanton sector at leading order in the semiclassical expansion. This lends support to the strongest version of a new prediction recently put forward on the basis of the...
متن کاملSuperconformal OPEs in D = 6 , Selection Rules and Non - renormalization Theorems
We analyse the OPE of any two 1/2 BPS operators of (2,0) SCFT 6 by constructing all possible three-point functions that they can form with another, in general long operator. Such three-point functions are uniquely determined by superconformal symmetry. Selection rules are derived, which allow us to infer " non-renormalization theorems " for an abstract superconformal field theory. The latter is...
