We make theoretical predictions for the recently introduced variable phi* corresponding to the azimuthal angle between leptons produced in the Drell-Yan process at the LHC. As a consequence of this work we are also able to generate results for the more commonly studied transverse momentum Q(T) of the lepton pair. Comparisons of these purely perturbative estimates for the Q(T) case yield good agreement with ATLAS and CMS data, as we demonstrate. We anticipate that this work will help stimulate measurements of phi* at the LHC. (c) 2012 Elsevier B.V. All rights reserved.

Abstract
We make theoretical predictions for the recently introduced variable phi* corresponding to the azimuthal angle between leptons produced in the Drell-Yan process at the LHC. As a consequence of this work we are also able to generate results for the more commonly studied transverse momentum Q(T) of the lepton pair. Comparisons of these purely perturbative estimates for the Q(T) case yield good agreement with ATLAS and CMS data, as we demonstrate. We anticipate that this work will help stimulate measurements of phi* at the LHC. (c) 2012 Elsevier B.V. All rights reserved.
