Description
There has been made tremendous progress in the automation of one-loop (or virtual) contributions to next-to-leading order (NLO) calculations in QCD, using both the conventional Feynman diagram approach as well as unitarity-based techniques. To have rates and distributions for observables at particle colliders at NLO accuracy also the real emission and subtraction terms have to be included in the calculation. Recently, two variations of subtraction schemes have been automated by several groups. In this talk these two schemes will be reviewed and there implementations discussed.
