摘要：

We explicitly calculate the leading order CP-odd effects from the standard model in the reaction p+pBAR --> W+/- + jet + X. We find that CP-violation in this reaction is of order 10(-8) within the standard model. We conclude that any experimental indication of CP-violation in the production of vector bosons at high-energy proton-antiproton colliders would be a clear signal for new physics.
