# Subtractions for NLO and NNLO QCD calculations

## by Dr. Lorena Rothen (Desy PostDoc)

Wednesday, May 3, 2017 from to (Europe/Berlin)
at DESY Hamburg ( Seminar Room 5 )
 Description Recently significant advances have been achieved in precision calculations for the LHC. I will motivate the necessity of NNLO precision to fully exploit the increasing accuracy of the data. The state of the art methods used in such fixed order calculations are subtractions. I will try to give you an overview using NLO calculations as a starting point. While NLO is generically solved, there are various different NNLO schemes on the market, each having its advantages and disadvantages.
