• The lighter scalar tau lepton τ^^~_1 may be the lightest scalar lepton and therefore would be found earlier in future collider experiments. We point out the impact of the measurement of the mass and the mixing angle of τ^^~ to discriminate the models of SUSY breaking. Furthermore, the measurement of the polarization of τ lepton(P_τ) from the decaying τ^^~_1 helps to determine the Yukawa sector of minimal supersymmetric standard model. We present our MC study of the production and the decay of τ^^~ lepton at a future linear collider at √<s>=500 GeV. The mass, mixing angle of τ^^~_1 and P_τ(τ^^~_1→τχ^0_1) would be measured precisely at the future LC.
