We discuss the comparisons of several kinematic distributions, measured by
the ATLAS and CMS Collaborations for dijet production, with the results
computed with three approaches: using a fixed next-to-leading order
calculation, with the POWHEG BOX and with HEJ. We study other interesting
kinematic distributions, exploring the effect of several sets of cuts. Previous
experimental studies have dealt with kinematic distributions where the
predictions of the three approaches were very similar. In this article, we
investigate kinematic distributions where the resummed effects in POWHEG and
HEJ are enhanced with respect to the fixed next-to-leading order result, since
different QCD-radiation regimes are probed, and we suggest a few kinematic
distributions where the predictions from POWHEG and HEJ are different, and
could be further investigated experimentally.
