Abstract: (Elsevier)
We calculate the gauge theory predictions in leading logarithmic approximation for the transverse momentum distribution of virtual photons produced via the Drell-Yan annihilation process. The leading contributions sum to a simple exponential form in agreement with a recent conjecture of Parisi and Petronzio and in disagreement with the finding of Dokshitser, D'Yakonov and Troyan.
