Based on 1.35x10(6) polarized Xi(-) events, we measure the parameter phi(Xi) to be -1.61degrees+/-2.66degrees+/-0.37degrees for the Xi(-)-->Lambdapi(-) decay. New results for the parameters beta(Xi) and gamma(Xi) are also presented. Assuming that the CP-violating phase difference is negligible, we deduce the strong phase difference between the P-wave and S-wave amplitudes of the Lambdapi final state to be 3.17degrees+/-5.28degrees+/-0.73degrees, reducing the uncertainty in estimating the level of CP violation in Xi-hyperon decay.
