Lectures on Scattering Amplitudes via AdS/CFT

Understand

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 is particularly appropriate for understanding the conformal properties of the amplitudes.
