چکیده

In this article we consider n gluon color ordered, planar amplitudes in N = 4 super Yang Mills at strong ’t Hooft coupling. These amplitudes are approximated by classical surfaces in AdS5 space. We compute the value of the amplitude for a particular kinematic configuration for a large number of gluons and find that the result disagrees with a recent guess for the exact value of the amplitude. Our results are still compatible with a possible relation between amplitudes and Wilson loops. In addition, we also give a prescription for computing processes involving local operators and asymptotic states with a fixed number of gluons. As a byproduct, we also obtain a string theory prescription for computing the dual of the ordinary Wilson loop, TrPe ∮

A Numerical Study of Gluon Scattering Amplitudes in N = 4 Super Yang-Mills Theory at Strong Coupling

We study gluon scattering amplitudes in N = 4 super Yang-Mills theory at strong coupling via the AdS/CFT correspondence. We solve numerically the discretized Euler-Lagrange equations on the square worldsheet for the minimal surface with light-like boundaries in AdS spacetime. We evaluate the area of the surface for the 4, 6 and 8-point amplitudes using worldsheet and radial cut-off regularizati...

Comment on the Alday-Maldacena solution in calculating scattering amplitude via AdS/CFT

Following the recent proposal of Alday and Maldacena to obtain the strong coupling scattering amplitude in N = 4 SYM theory via AdS/CFT, we point out that a unique solution can be obtained by imposing all the Virasoro constraints. This solution is identical to the Alday-Maldacena solution for the four-point case which is in accordance with the ansatz of Bern, Dixon and Smirnov. We show that thi...

Gluon scattering inN = 4 super-Yang-Mills theory from weak to strong coupling

I describe some recent developments in the understanding of gluon scattering amplitudes in N = 4 super-Yang-Mills theory in the large-Nc limit. These amplitudes can be computed to high orders in the weak coupling expansion, and also now at strong coupling using the AdS/CFT correspondence. They hold the promise of being solvable to all orders in the gauge coupling, with the help of techniques ba...

Lectures on Scattering Amplitudes via AdS/CFT

We review recent progress on computing scattering amplitudes of planar N = 4 super Yang-Mills at strong coupling by using the AdS/CFT duality. We do explicit computations by using both, dimensional regularization and a cut-off in the radial direction. Up to an additive constant independent on the kinematics, the finite piece of the amplitude is the same in both regularizations. The later scheme...

Gluon 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...
