Description
I will present a new subtraction method for next-to-leading order calculations that is particularly convenient when narrow resonances are present. The method is suitable for the implementation of next-to-leading order calculations matched to parton shower generators. It allows at the same time for the inclusion of all finite width effects, including interferences, and for a consistent treatment of resonances in the shower approach, preserving the mass of resonances near their peak. We implement our method, in a fully general and automatic way, within the POWHEG BOX framework, and illustrate it on single-top and top-pair production at the LHC.
