Abstract
We calculate the NNLO QCD corrections to diphoton production with an
additional jet at the LHC. Our calculation represents the first NNLO-accurate
prediction for the transverse momentum distribution of the diphoton system. The
improvement in the accuracy of the theoretical prediction is significant, by a
factor of up to four relative to NLO QCD. Our calculation is exact except for
the finite remainder of the two-loop amplitude which is included at leading
color. The numerical impact of this approximated contribution is small. The
results of this work are expected to further our understanding of the Higgs
boson sector and of the behavior of higher-order corrections to LHC processes.
