Parity-nonconserving asymmetries appear in the angular distribution of the charged leptons from the decay of W bosons produced with high transverse momentum in hadron colliders. Absorptive parts of the amplitudes which produce the nonvanishing asymmetry are calculated in the one-loop order. The asymmetries grow rapidly with the W transverse momentum qT and reach a 5% level at qT∼20 GeV. Measurements of the sign of the asymmetries will distinguish clearly between V-A and V+A couplings without polarization experiments.
