Comment on `A collider signature of the supersymmetric golden region'

Abstract

We show that $Z$ polarization measurement is useful for distinguishing the signal decay chain of the `golden region' in the minimal supersymmetric standard model(MSSM) parameter space, which involves the stop decay of ${\tilde{t}}_2\to {\tilde{t}}_1+Z$, from other decay chains involving the neutralino decay of ${\tilde{\chi }}_2^0\to {\tilde{\chi }}_1^0+Z$ in different MSSM scenarios.
