摘要：

The effects of soft gluon brehmsstrahlung on the k⊥ distributions of μ pairs produced in hadron-hadron collisions are studied using the Block-Nordsiek method. At moderate energies we obtain a good fit to present experimental data by adjusting the values of two phenomenological parameters. At quite large energies the predictions are independent of specific values assigned to the parameters and the whole p⊥ distribution, including p⊥ {reversed tilde equals} 0, turns out to be computable. © 1979.
