Abstract

We study the azimuthal correlation of hadron pairs produced in hadron-hadron collisions in the framework of perturbative QCD. We concentrate our attention on the `almost back-to-back' region where resummation of large logarithms due to soft and/or collinear radiation are shown to play an important role. Our aim is to perform perturbative resummation at single logarithmic accuracy.
