Description

Precise predictions for total and differential cross sections
at hadron colliders became an important corner stone of the LHC physics.
The lack of new 'smoking-gun' physics signals
requires precise comparisons between measurements and Standard Model
predictions to get a
handle on new physics effects. Tremendous efforts have been made to push
perturbative calculations to higher orders such that NNLO QCD calculations are
now state-of-art for most 2 $\to$ 1 and 2 $\to$ 2 hard scattering processes.
Upcoming five-point two-loop amplitudes and refined subtractions schemes for
real radiation contributions allow first steps in the direction of 2 $\to$ 3
scattering processes.
I present novel NNLO QCD results for 2 $\to$ 3 processes obtained with the
Sector-improved Subtraction Scheme and their phenomenological application.
