Correlators of Short Multi-Trace Operators in N=4 Supersymmetric Yang-Mills
Abstract
Multi-trace scalar operators in the (0,k,0) representations of SU(4)R share many properties with their single-trace analogs. These multi-trace operators are primary fields of short representations of the N=4 superconformal group. Thus, they have protected dimensions. We show that two- and three-point correlator functions of such operators do not receive radiative corrections at order g2 in perturbation theory for an arbitrary gauge group.
