# Lectures on scattering amplitudes via AdS/CFT

@article{Alday2008LecturesOS, title={Lectures on scattering amplitudes via AdS/CFT}, author={Luis F. Alday}, journal={Fortschritte der Physik}, year={2008}, volume={56} }

We review recent progress on computing scattering amplitudes of planar đ© = 4 super YangâMills at strong coupling by using the AdS/CFT duality. We consider in detail the scattering of four gluons and do explicit computations by using both, dimensional regularization and a cutâoff in the radial direction. The later scheme is particularly appropriate for understanding the conformal properties of the amplitudes.Â
