From Amplitudes to Form Factors in the N=4 Sym Theory
In the past few years, much attention has been given to studying the planar limit for the scattering amplitudes in the N=4 supersymmetric Yang–Mills (SYM) theory. It is believed that the hidden symmetries responsible for integrability properties of the N=4 SYM theory completely fix the structure of the amplitudes (the S-matrix of the theory) [1]. In particular, this is manifested in the fact th...
متن کاملComments on the β - deformed N = 4 SYM Theory
Several calculations of 2and 3-point correlation functions in the deformed theory are presented. The central charge in the LuninMaldacena gravity dual is shown to be independent of the deformation parameter. Calculations show that 2and 3-point functions of chiral primary operators have no radiative corrections to lowest order in the interactions. Correlators of the operator tr(Z1Z2), which has ...
متن کاملSL ( 2 , Z ) multiplets in N = 4 SYM theory
We discuss the action of SL(2, Z) on local operators in D = 4, N = 4 SYM theory in the superconformal phase. The modular property of the operator’s scaling dimension determines whether the operator transforms as a singlet, or covariantly, as part of a finite or infinite dimensional multiplet under the SL(2, Z) action. As an example, we argue that operators in the Konishi multiplet transform as ...
متن کاملNew results in the deformed N = 4 SYM theory
We investigate various perturbative properties of the deformed N = 4 SYM theory. We carry out a three-loops calculation of the chiral matter superfield propagator and derive the condition on the couplings for maintaining finiteness at this order. We compute the 2-, 3-and 4-point functions of composite operators of dimension 2 at two loops. We identify all the scalar operators (chiral and non-ch...
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...
