  Around 1999, thanks to the RHIC Spin Collaboration (RSC), the Relativistic
Heavy Ion Collider (RHIC) will be used as a polarized proton-proton collider. A
new handed interaction between quark subconstituents, which could explain the
excess of large E_T jet found by the CDF collaboration, could be at the origin
of some small parity violating effects in one-jet inclusive production. Using
spin asymmetries it is possible, at RHIC, to disentangle this new effect from
the Standard Model prediction due to QCD-ElectroWeak interferences.
