We propose the measurement of the ratio RCSS(QminT) ≡ σ(QT>QminT)/σTotal to study the effects of the multiple soft gluon radiation, predicted by QCD, on the transverse momentum (QT) distribution of the weak gauge bosons W± and Z0 produced at the Tevatron. We compare the prediction of the extended Collins-Soper-Sterman resummation formalism with the next-to-leading and next-to-next-to-leading order calculations. We show that both the rich dynamics of the QCD multiple soft gluon radiation and the non-perturbative sector of QCD can be tested by measuring RCSS.
