摘要：

We discuss the optimization of the Drell-Yan pair production cross section calculated at O(αs) and compare it with the O(αs2) results of van Neerven et al. It is shown that the optimized predictions do agree analytically with the latter calculation near the phase space boundary. They also provide a good numerical approximation wherever the stability equations have a solution. © 1990 Springer-Verlag.
