We consider transverse momentum (qT) resummation for Drell-Yan lepton pair production at hadron colliders. We discuss the resummation of logarithmic-enhanced QCD corrections at small values of qT and the matching procedure to consistently combine resummation with the fixed order perturbative result at intermediate and large qT. We present a study of the scale dependence and of the perturbative uncertainty of our results. We compare numerical results for e+e- pairs from the decay of Z bosons with the available Tevatron data and show our predictions for the LHC.
