The recent results for R = σ W + 1 j e t /σ W + 0 j e t s obtained by the D Collaboration at Fermilab are reanalyzed. We use Pade Approximants (PA) to estimate the higher-order QCD corrections, which we find are on the order of 4%. We observed that using PA, we obtain the predictions of R increased by approximately 4%, independent of parton distribution functions used in the prediction, and are consistently lower by about one standard deviation compared to the experimental result. In addition, they are independent of the values of α s (M z ) used in the parton distribution function fits.
