Comments 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 کاملGluon Scattering in Deformed N = 4 Sym *
We consider gluon and gluino scattering amplitudes in large N β-deformed N = 4 SYM with real β. A direct inspection of the planar diagrams shows that the scattering amplitudes to all orders in perturbation theory are the same as in the undeformed N = 4 SYM theory. Using the dual σ-model description, we find the same equality at strong coupling to all orders in the σ-model loop expansion. Finall...
متن کاملFinite - size effects in the superconformal β - deformed N = 4 SYM
We study finite size effects for composite operators in the SU(2) sector of the superconformal β-deformed N = 4 SYM theory. In particular we concentrate on the spectrum of one single magnon. Since in this theory one-impurity states are non BPS we compute their anomalous dimensions including wrapping contributions up to four loops and discuss higher order effects. ∗[email protected]...
متن کاملSingle impurity operators at critical wrapping order in the β - deformed N = 4 SYM
We study the spectrum of one single magnon in the superconformal βdeformedN = 4 SYM theory in the planar limit. We compute the anomalous dimensions of one-impurity operators O1,L = tr(φZ), including wrapping contributions at their critical order L. ∗[email protected] [email protected] [email protected] [email protected]
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...
