Azimuthal correlation in DIS
arXiv:hep-ph/0207072
Abstract
We introduce a new angular correlation in DIS process and study its differential distribution in the region in which the observable is small. We perform a perturbative resummation at single logarithmic accuracy and estimate leading non-perturbative power corrections.
