Description

The transverse-momentum (QT) distribution of low-mass Drell-Yan pairs is calculated in QCD perturbation theory with all-order resummation of αs(αs ln(QT2/Q2))n type terms. We demonstrate that the rapidity distribution of low-mass Drell-Yan pairs at large-enough transverse momentum is an advantageous source of constraints on the gluon distribution and its nuclear dependence. We argue that low-mass Drell-Yan pairs in the forward region provide a good and clean probe of small-x gluons at collider energies
