Precision Study of MSSM at Future e^{+}e^{} Linear Colliders
Abstract
The lighter scalar tau lepton tilde{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 tilde{τ} to discriminate the models of SUSY breaking. Furthermore, the measurement of the polarization of τ lepton(P_{τ}) from the decaying tilde{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 tilde{τ}_{1} lepton at a future linear collider at sqrt{s} = 500 GeV. The mass, mixing angle of tilde{τ}_{1} and P_{τ}(tilde{τ}_{1} rightarrow τ χ_{1}^{0}) would be measured precisely at the future LC.
