Local analytic sector subtraction in the making


In this talk, I will present the status of the art of the “local analytic sector subtraction” scheme, a novel universal method to practically achieve the cancellation of infrared singularities in high energy QCD. I will focus in particular on the complete formulation at NLO and on the results for final state radiation at NNLO. I will also show how the universality of this scheme is particularly suited to understand the general structure of subtraction algorithms and their connection to the all-order factorisation of scattering amplitudes into soft, collinear and hard factors..
