Parity-odd asymmetries in W-jet events at the fermilab tevatron

Parity-odd asymmetries in the decay angular distribution of a W boson produced with a hard jet in ppover ] collisions arise only from QCD rescattering effects. If observed, these asymmetries will provide a first demonstration that perturbative QCD calculation is valid for the absorptive part of scattering amplitudes. We propose a simple observable to measure these asymmetries and perform realistic Monte Carlo simulations at energies reached at the Fermilab Tevatron. It is shown that the Tevatron run II should provide sufficient statistics to test the prediction.
