摘要：

A quantity that promises to reveal important information on perturbative and non-perturbative QCD dynamics is the azimuthal decorrelation between jets in different hard processes. In order to access this information fixed-order NLO predictions need to be supplemented by resummation of logarithmic terms which are large in the region where the jets are nearly back-to-back in azimuth. In the present Letter we carry out this resummation to next-to-leading logarithmic accuracy explaining the important role played by the recombination scheme in general resummations for such jet observables.
