Title: Binary black holes and quantum off-shell recursions

Abstract: The quantum off-shell recursion provides an efficient and universal computational tool for loop-level scattering amplitudes. I will present a new comprehensive computational framework based on the quantum off-shell recursion for binary black hole systems. I’ll also discuss a new method of identifying classical diagrams and a classification scheme that optimizes the integration by parts reduction process. I’ll show how to apply the framework to the classical scalar 2 → 2 amplitudes up to the 3PM order.
