Low mass lepton pair production in hadron collisions
Description
The hadroproduction of lepton pairs with mass Q and transverse momentum QT can be described in perturbative QCD by the same partonic subprocesses as prompt photon production. They demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region QT > 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
