Lectures on celestial amplitudes

ISIMA lectures on celestial mechanics. 3

To understand the formation and evolution of exoplanet systems, we would like to have empirical theoretical tools for predicting whether a given planetary system is stable—or, more precisely, what is its lifetime before some catastrophic event such as a collision or ejection—without having to integrate the planetary orbits for the lifetime of the host star. There are two discouraging lessons fr...

TASI Lectures on Scattering Amplitudes

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...
