Resumen

We present the first combined measurement of the rapidity and transverse momentum dependence of dijet azimuthal decorrelations, using the recently proposed quantity R_dff. The variable R_dff measures the fraction of the inclusive dijet events in which the azimuthal separation of the two jets with the highest transverse momenta is less than a specified value for the parameter dffmax. The quantity R_dff is measured in pp collisions at s = 1.96 TeV, as a function of the dijet rapidity interval, the total scalar transverse momentum, and dffmax. The measurement uses an event sample corresponding to an integrated luminosity of 0.7 fb^-1 collected with the D0 detector at the Fermilab Tevatron Collider. The results are compared to predictions of a perturbative QCD calculation at next-to-leading order in the strong coupling with corrections for non-perturbative effects. The theory predictions describe the data, except in the kinematic region of large dijet rapidity intervals and large dffmax.
