Local Unitarity: a representation of differential cross-sections that is locally free of infrared singularities at any order
Abstract We propose a novel representation of differential scattering cross-sections that locally realises the direct cancellation of infrared singularities exhibited by its so-called real-emission and virtual degrees of freedom. We take advantage of the Loop-Tree Duality representation of each indi...
