Infrared subtraction and factorisation beyond NLO in QCD
Abstract: I present a method for the local subtraction of infrared divergences at next-to-next-to-leading order (NNLO) in QCD that aims at minimising the complexity of the problem by combining a partition of the phase space with the possibility to achieve an easy analytic integration of the ensuing subtraction counterterms. A connection between infrared subtraction and factorisation of scattering amplitudes to all orders in perturbation theory is then traced, enabling the formal construction of subtraction schemes beyond NNLO
