Title: $$\sin^2\theta^{\rm lept}_{\rm eff}$$ and $M_W$(indirect) extracted from 9 fb$$^{-1}$$ $$\mu^+\mu^-$$ event sample at CDF

We report on the extraction of $$\sin^2\theta^{\rm lept}_{\rm eff}$$ and indirect measurement of the mass of the W boson from the forward-backward asymmetry of $$\mu^+\mu^-$$ events in the $Z$ boson mass region. The data sample collected by the CDF detector corresponds to the full 9 fb$$^{-1}$$ run II sample. We measure $$\sin^2 \theta^{\rm lept}_{\rm eff} = 0.2315 \pm 0.0010$$, $$ \sin^2 \theta_W = 0.2233 \pm 0.0009$$ and $$M_W ({\rm indirect}) = 80.365 \pm 0.047 \;{\rm GeV}/c^2$$, where each uncertainty includes both statistical and systematic contributions. Comparison with the results of the D0 collaboration are presented.
