Low mass lepton pair production in hadron collisions

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

The hadroproduction of lepton pairs with mass QQ and transverse momentum QTQ_T can be described in perturbative QCD by the same partonic subprocesses as prompt photon production. We demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region QT>Q/2Q_T>Q/2. This leads to sensitivity to the gluon density in kinematical regimes that are accessible both at collider and fixed target experiments while eliminating the theoretical and experimental uncertainties present in prompt photon production.
