Simplifications of four-point functions in N = 4 supersymmetric Yang-Mills theory at two loops
The superconformal Ward identities combined with N = 2 harmonic analyticity are used to evaluate two-loop four-point correlation functions of gauge-invariant operators in D = 4, N = 4 supersymmetric Yang-Mills theory in terms of the well-known one-loop box integral. The result is confirmed by a direct numerical computation. URA 1436 associée à l’Université de Savoie Supersymmetric Yang-Mills (S...
متن کاملFour - point functions in N = 4 supersymmetric Yang - Mills theory at two loops
Four-point functions of gauge-invariant operators in D = 4, N = 4 supersymmetric Yang-Mills theory are studied using N = 2 harmonic superspace perturbation theory. The results are expressed in terms of differential operators acting on a scalar two loop integral. The leading singular behaviour is obtained in the limit that two of the points approach one another. We find logarithmic singularities...
متن کامل2 00 1 Wilson Loops in N = 4 Supersymmetric Yang - Mills Theory from Random Matrix Theory
Based on the AdS/CFT correspondence, string theory has given exact predictions for circular Wilson loops in U (N) N = 4 supersymmetric Yang-Mills theory to all orders in a 1/N expansion. These Wilson loops can also be derived from Random Matrix Theory. In this paper we show that the result is generically insensitive to details of the Random Matrix Theory potential. We also compute all higher k-...
متن کاملPomeron Eigenvalue at Three Loops in N=4 Supersymmetric Yang-Mills Theory.
We obtain an analytical expression for the next-to-next-to-leading order of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) Pomeron eigenvalue in planar N=4 SYM using quantum spectral curve (QSC) integrability-based method. The result is verified with more than 60-digit precision using the numerical method developed by us in a previous paper [N. Gromov, F. Levkovich-Maslyuk, and G. Sizov, arXiv:1504.0...
متن کاملQuenched Two Dimensional Supersymmetric Yang-Mills Theory
By studying the pure Yang-Mills theory on a circle, as well as an adjoint scalar coupled to the gauge field on a circle, we propose a quenching prescription in which the combination of the spatial component of the gauge field and P is treated as a dynamic variable. Averaging over momentum is not necessary, therefore the usual ultraviolet cut-off is eliminated. We then apply this prescription to...
