Spin asymmetries in one-jet production at RHIC with polarized proton beams: the effects of a hadrophilic Z′

We show that the measurement of some parity violating asymmetry in the production of a large Et jet could reveal the presence of a new hadrophilic Z′ such as the one recently introduced to interpret possible departures from the Standard Model predictions both at LEP and at CDF. Such a measurement could be performed within a few years by the RHIC Spin Collaboration (RSC) using the Relativistic Heavy Ion Collider (RHIC) as a polarized proton-proton collider.
