Transverse-momentum resummation: A perturbative study of Z production at the Tevatron

We consider transverse-momentum (qT) resummation for Drell-Yan lepton pair production in hadron collisions. At small values of qT, the logarithmically-enhanced QCD contributions are resummed up to next-to-leading logarithmic accuracy. At intermediate and large values of qT, resummation is consistent...
