Parity-Odd Asymmetries in W-Jet Events at the Tevatron
Kaoru Hagiwara, Ken-ichi Hikasa, Hiroshi Yokoya
Abstract
Parity-odd asymmetries in the decay angular distribution of a W boson produced with a hard jet in pp 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 Tevatron energies. It is shown that the Tevatron Run-II should provide sufficient statistics to test the prediction.
