  The QCD predictions for single-inclusive jet production are computed with
joint resummation of threshold and jet radius logarithms. The results are
compared to those based on fixed order perturbation theory up to
next-to-next-to-leading order and to data by the CMS collaboration measured in
proton-proton collisions at the LHC at $\sqrt{S}=8$ TeV. The joint resummation
results are in remarkable agreement with the data.
