Integrating double soft emissions for NNLO computations — •Maximilian Delto and Kirill Melnikov — Institut für Theoretische Teilchenphysik, Karlsruhe Institute of Technology (KIT)

We will describe an analytic calculation of the phase-space integral of the double soft eikonal function in dimensional regularisation required for fully-differential next-to-next-to-leading order computations in QCD. We will consider cases when the radiating partons are in a back-to-back kinematics, relevant for Drell-Yan and Higgs production, and when the radiating partons are at an arbitrary angle, relevant e.g. for DIS and weak boson fusion processes.
