Correlators of short multitrace operators in N=4 supersymmetric Yang-Millstheory - art. no. 105038

Multitrace scalar operators in the (0,k,0) representations of SU(4)(R) shar e many properties with their single-trace analogues. These multitrace opera tors are primary fields of short representations of the N = 4 superconforma l group. Thus, they have protected dimensions. We show that two- and three- point correlator functions of such operators do not receive radiative corre ctions at order g(2) in perturbation theory for an arbitrary gauge group.
