In a N = 1 superspace formulation of N = 4 Yang-Mills theory we obtain the anomalous dimensions of chiral operators with large R charge J â†’âˆž keeping g2N/J2 finite, to all orders of perturbationâ€¦ (More)

We present the planar four-loop anomalous dimension of the composite operator tr(Ï† [Z,Ï†]Z) in the flavour SU(2) sector of the N = 4 SYM theory. At this loop order wrapping interactions are present:â€¦ (More)

We study the spectrum of one single magnon in the superconformal Î²deformed N = 4 SYM theory in the planar limit. We compute the anomalous dimensions of one-impurity operators O1,L = tr(Ï†Z), includingâ€¦ (More)

We compute two-point functions of chiral operators TrÎ¦3 in N = 4 SU(N) supersymmetric Yang-Mills theory to the order g4 in perturbation theory. We perform explicit calculations using N = 1 superspaceâ€¦ (More)

In the Î²-deformed N = 4 supersymmetric SU(N) Yang-Mills theory we study the class of operators OJ = Tr(Î¦ J i Î¦k), i 6= k and compute their exact anomalous dimensions for N,J â†’ âˆž. This leads to aâ€¦ (More)

We compute twoâ€“point functions of lowest weight operators at the nextâ€“toâ€“leading order in the couplings for the Î²â€“deformed N = 4 SYM. In particular we focus on the CPO Tr(Î¦1) and the nonâ€“CPO Tr(Î¦1Î¦2)â€¦ (More)

We study the gauge transformation of the recently computed one-loop four-point function of N = 4 supersymmetric Yang-Mills theory with gauge group U(N). The contributions from nonplanar diagrams areâ€¦ (More)

For N = 1 SU(N) SYM theories obtained as marginal deformations of the N = 4 parent theory we study perturbatively some sectors of the chiral ring in the weak coupling regime and for finite N . Byâ€¦ (More)

We study the N = 1 SU(N) SYM theory which is a marginal deformation of the N = 4 theory, with a complex deformation parameter Î². We consider the large N limit and study perturbatively the conformalâ€¦ (More)

We study finite size effects for composite operators in the SU(2) sector of the superconformal Î²-deformed N = 4 SYM theory. In particular we concentrate on the spectrum of one single magnon. Since inâ€¦ (More)
