Then we study the parity violating effects, for jet production in polarized e h pp collisions at RHIC, which could be due to the presence of quark subconstituents or : v new massive gauge bosons. We emphasize that the measurement of spin asymmetries in i X such a polarized context could give some crucial informations on the chiral structure of r these hypothetical new interactions. a To appear in the proceedings of the Workshop ”Beyond the Desert”, Ringberg, Germany, June 1997.
