We explore the sensitivity and the physical interest of the measurement of parity-violating spin asymmetries in one-jet production in the presence of a new leptophobic neutral gauge boson, Z', within polarized hadronic collisions at the BNL RHIC. We focus on polarized neutron collisions which could be achieved in a realistic upgrade of the RHIC-spin program. We show that, in the case of a discovery, a compilation of the information coming from both polarized (p) over right arrow(p) over right arrow and (n) over right arrow(n) over right arrow collisions should constrain the number of Higgs doublets and the presence or absence of trilinear fermion mass terms in the underlying model of new physics.
