Description
We compute N=4 Super Yang Mills planar amplitudes at
strong coupling by considering minimal surfaces in AdS_5
space. The surfaces end on a null polygonal contour at the
boundary of AdS. We show how to compute the area of the
surfaces as a function of the conformal cross ratios
characterizing the polygon at the boundary. These
equations have the form of Thermodynamic Bethe Ansatz
equations. The area is the free energy of the TBA system.
We consider any number of gluons and in any kinematic
configuration.
