DISCOVERY LIMITS FOR A NEW CONTACT INTERACTION AT FUTURE HADRONIC COLLIDERS WITH POLARIZED BEAMS

The production of high-transverse energy jets in hadron-hadron collisi ons is sensitive to the presence of new contact interactions between q uarks, If proton polarization were available, the measurement of some parity-violating spin asymmetries in one-jet production at large trans verse energy would complement the usual search for deviations from the expected QCD cross section. At the same time, unique information on t he chirality structure of the new interaction could be obtained. In th is context, we compare the potentialities of various pp and pp collide rs that an planned or have been proposed. with the additional requirem ent of beam polarization.
