Theory SeminarInfrared subtraction beyond NLO
Paolo Torrielli (University of Torino)
I present a new method for the local subtraction of infrared divergences at next-to-next-to-leading order (NNLO) in QCD. The method aims at minimising the complexity of the problem through a partition of the phase space, still allowing an 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 construction of subtraction counterterms beyond NNLO.
