  Both the ATLAS and CMS Collaborations have sought for effects beyond pure
next-to-leading order in dijet observables, with the goal to distinguish
between the perturbative descriptions provided by a next-to-leading order plus
collinear-resummation calculation and by the resummation of wide-angle, hard
emissions. In this paper we identify regions of phase space in dijet production
where some observables receive large corrections beyond next-to-leading order
and study their theoretical description with two tools that perform these two
different resummations: the POWHEG BOX and HEJ. Furthermore, we suggest
analyses where the predictions from POWHEG and HEJ can be clearly distinguished
experimentally.
