چکیده
We analyze the operator product expansion Tμν(z)W [C] in N = 4 4-dimensional Super-Yang-Mills(SYM) theory with U(N) gauge group, and clarify that the closed Wilson loop does not possess an anomalous dimension and that only the shape of the loop is changed by the conformal transformation.

Ope between the Energy-momentum Tensor and the Wilson Loop in N = 4 Super-yang-mills Theory Typeset Using Ptpt E X.sty <ver.1.0> 2
Conformal field theory (CFT) is important in modern particle physics in various contexts. The most powerful tool in the 2-dimensional CFT is the operator product expansion (OPE). The OPE between the energy-momentum tensor and an operator extracts its conformal weight. We find it interesting to consider the similar issue with respect to the Wilson loop in a conformally invariant Yang-Mills theor...
متن کاملWilson loop correlators at strong coupling: from matrices to bubbling geometries
We compute at strong coupling the largeN correlation functions of supersymmetric Wilson loops in large representations of the gauge group with local operators of N = 4 super Yang-Mills. The gauge theory computation of these correlators is performed using matrix model techniques. We show that the strong coupling correlator of the Wilson loop with the stress tensor computed using the matrix model...
متن کاملGluon scattering in N = 4 Super Yang-Mills at finite temperature
We extend the AdS/CFT prescription of Alday and Maldacena to finite temperature T , defining an amplitude for gluon scattering in N = 4 Super Yang-Mills at strong coupling from string theory. It is defined by a lightlike ”Wilson loop” living at the horizon of the T-dual to the black hole in AdS space. Unlike the zero temperature case, this is different from the Wilson loop contour defined at th...
متن کاملImplementation of the duality between Wilson loops and scattering amplitudes in QCD.
We generalize modern ideas about the duality between Wilson loops and scattering amplitudes in N=4 super Yang-Mills theory to large-N (or quenched) QCD. We show that the area-law behavior of asymptotically large Wilson loops is dual to the Regge-Veneziano behavior of scattering amplitudes at high energies and fixed momentum transfer, when the quark mass is small and/or the number of particles i...
متن کاملThe N=4 Quantum Conformal Algebra
We determine the spectrum of currents generated by the operator product expansion of the energy-momentum tensor in N=4 super-symmetric Yang-Mills theory. Up to the regular terms and in addition to the multiplet of the stress tensor, three current multiplets appear, Σ, Ξ and Υ, starting with spin 0, 2 and 4, respectively. The OPE’s of these new currents generate an infinite tower of current mult...
