Abstract

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.

  42. While in principle X can vary from 0 to 1, it can be shown that, for a partonic 2→n process, the lower limit is not 0 but 1/(n−1), so that, in our study (n=3), 1/2≤X≤1.

  43. We used PYTHIA 6.4.25 with the AMBT1 tune.
