Abstract

The transverse momentum properties of Drell-Yan pairs produced in hadronic collisions are analyzed in QCD by combining the soft gluon description at low p⊥ with hard parton effects at high p⊥. Soft gluon effects, implemented by exact kinematics considerations, play a very important role in the analysis and describe the main features of the data. Recently calculated αs2 corrections to the annihilation terms improve the agreement with data at large p⊥ for π−N collisions. Predictions are also made for pp annihilation at collider energies.
