Another Leigh-Strassler deformation through the Matrix model
In here the matrix model approach, by Dijkgraaf and Vafa, is used in order to obtain the effective superpotential for a certain deformation of N=4 SYM discovered by Leigh and Strassler. An exact solution to the matrix model Lagrangian is found and is expressed in terms of elliptic functions.
متن کاملThe Leigh-Strassler Deformation and the Quest for Integrability
In this paper we study the one-loop dilatation operator of the full scalar field sector of Leigh-Strassler deformed N=4 SYM theory. In particular we map it onto a spin chain and find the parameter values for which the Reshetikhin integrability criteria are fulfilled. Some years ago Roiban found an integrable subsector, consisting of two holomorphic scalar fields, corresponding to the XXZ model....
متن کامل2 00 7 Conformal Invariance in the Leigh - Strassler deformed N = 4 SYM Theory
We consider a full Leigh-Strassler deformation of the N = 4 SYM theory and look for conditions under which the theory would be conformally invariant and finite. Applying the algorithm of perturbative adjustments of the couplings we construct a family of theories which are conformal up to 3 loops in the non-planar case and up to 4 loops in the planar one. We found particular solutions in the pla...
متن کاملChiral primaries in the Leigh - Strassler deformed N = 4 SYM – a perturbative study
We look for chiral primaries in the general Leigh-Strassler deformed N = 4 super Yang-Mills theory by systematically computing the planar one-loop anomalous dimension for single trace operators up to dimension six. The operators are organised into representations of the trihedral group, ∆(27), which is a symmetry of the Lagrangian. We find an interesting relationship between the U(1)R-charge of...
متن کاملA note on perturbative aspects of Leigh - Strassler deformed N = 4 SYM theory
We carry out a perturbative study of the Leigh-Strassler deformed N = 4 SYM theory in order to verify that the trihedral ∆(27) symmetry holds in the quantum theory. We show that the ∆(27) symmetry is preserved to two loops (at finite N) by explicitly computing the superpotential. The perturbative superpotential is not holomorphic in the couplings due to finite contributions. However, there exis...
