Four representative models - \\chi,\\psi, \\eta, \\nu models - are studied in some detail. We find that the improved data of parity violation in cesium atom, which is 2.2-\\sigma away from the Standard Model (SM) prediction, could be explained by the exchange of the heavy mass eigenstate Z_2 in the intermediate state.
