Local analytic sector subtraction for final state radiation at NNLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We present recent developments of the local analytic sector subtraction of infrared singularities for final state real radiation at NNLO in QCD.
Factorisation and Subtraction beyond NLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We provide a general method to construct local infrared subtraction counterterms for unresolved radiative contributions to differential cross sections, to any order in perturbation…
Local Analytic Sector Subtraction at NNLO
Lorenzo Magnea, Ezio Maina, Giovanni Pelliccioli +3
We present a new method for the local subtraction of infrared divergences at next-to-next-to-leading order (NNLO) in QCD, for generic infrared-safe observables. Our method attempts…
Factorization and subtraction
Lorenzo Magnea, Ezio Maina, Paolo Torrielli +1
We explore the connection between the factorisation of virtual corrections to multi-particle massless gauge theory amplitudes and the problem of subtraction at NNLO and beyond. Tak…
