NLO predictions for dijet azimuthal correlations — •Armando Bermudez Martinez, Daniela Dominguez Damiani, and Hannes Jung — DESY, Hamburg, Germany
Factorization theorems and the matching of matrix elements (ME) to parton showers (PS) are highly relevant topics of discussion especially in the simulation of hadron collider physics. For the study of possible breaking of factorization the so-called resummation region is particularly interesting. Within perturbative QCD, the resummation or Sudakov regions are sectors of the phase space where any fix order calculation does not give a reliable result and an all order computation approach is needed. MC generators implement this "all order" approximate calculation by means of PS. Here we present a study of the inclusive dijet cross section as a function of the azimuthal separation between the leading jets. We focus on the Sudakov region for high pt leading jets scenarios. The studies were performed using 3 final partons @ NLO ME as well as POWHEG three jets NLO matched to pt ordered PS.
