HEP Student Seminar: Subtractions for NLO and NNLO QCD calculations

by Dr Lorena Rothen (Desy PostDoc)

Wednesday 3 May 2017, 16:00 → 17:00 Europe/Berlin

Seminar Room 5 (DESY Hamburg)

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.
