To offer a possible resolution to the apparent discrepancy between the experimental and the theoretical values of the W + 1 jet to W + 0 jets ratio reported by the 0 group, we examine the effects of the multiple soft gluon radiation on the W boson production at the Tevatron. Based on the calculation of the W boson transverse momentum (Qₜ) distribution in the Collins-Soper-Sterman resummation formalism, we conclude that the effect of the soft gluon radiation is important in the region of Qₜ < 50 GeV, and it can be better tested by a more inclusive observable RCSS(Qₜ)≡ σ(Qₜ>Qₜ)σTotal.
