In recent years, great progress has been made on computing rates for production processes of direct relevance to experiments at the Large Hadron Collider (LHC), as well as on modeling waveforms for gravitational-wave signals from compact binary systems. The understanding and ability to compute scattering amplitudes and classical observables has been important for linking those seemingly unrelated topics. As a consequence, we are witnessing remarkable advances in both fields.

The aim of the School is to bring together young theorists working on LHC physics with those working on gravitational
