The production of high-transverse energy jets in hadron-hadroncollisions is
sensitive to the presence of new contact interactions between quarks. If proton
polarization were available, the measurement of some parity violating spin
asymmetries in one-jet production at large transverse energy would complement
the usual search for deviations from the expected QCD cross section. In the
same time, a unique information on the chirality structure of the new
interaction could be obtained. In this context, we compare the potentialities
of various pp and ppˉ​ colliders that are planned or have been proposed,
with the additional requirement of beam polarization.Comment: Latex file, 9 pages and 1 ps fig, definition of the subprocess
variables and one example of the effect of new contact terms on the parity
violating spin asymmetry are added. Eq. 8 (now eq. 9) and the following
equation are changed, giving better bounds in the polarized pp case (new
