We report on a measurement of σ(pp¯→W + X)B(W →τν) in collisions at √s = 1.8 TeV at the Fermilab Tevatron. The measurement is based on an integrated luminosity (lum) of 18pb1 of data collected with the D0 detector during 1994–1995. We find that σ(pp¯→W + X)B(W →τν) = 2.22±(stat)±0.10(syst)±0.10(lum)nb. Lepton universality predicts that the ratio of the tau and electron electroweak charged current couplings to the W boson, gτW, be unity. We find = 0.980±0.031, in agreement with lepton universality.
