Snowmass White Paper: String Perturbation Theory

Authors: Nathan Berkovits, Eric D'Hoker, Michael B. Green, Henrik Johansson, Oliver Schlotterer Preprint number: UUITP-13/22 Abstract: The purpose of this White Paper is to review recent progress towards elucidating and evaluating string amplitudes, relating them to quantum field theory amplitudes, applying their predictions to string dualities, exploring their connection with gravitational physics, and deepening our understanding of their mathematical structure. We also present a selection of targets for future research.
