TRIPLE-PRODUCT SPIN-MOMENTUM CORRELATIONS IN POLARIZED Z DECAYS TO THREE JETS.
A. Brandenburg, L. Dixon, Y. Shadmi
Abstract
We discuss hard rescattering effects that can be measured using CP-even, T N-odd triple-product observables in polarized Z decays to three jets. We show that the standard model contributions, from both QCD and electroweak rescattering, are very small. Thus these measurements are potentially sensitive to physics beyond the standard model. We investigate one such contribution which involves a new gauge boson coupling to baryon number.
