W mass and Leptonic Z-decays in the NMSSM

Florian Domingo, Teresa Lenz

We study a subset of electroweak-precision observables consisting of $M_W$, ${\sin }^2{\theta }_{eff}^{\tau }$, $BR(Z\to {\tau }^{+}{\tau }^{-})$ and $\Gamma (Z\to {\tau }^{+}{\tau }^{-})/\Gamma (Z\to e^{+}{e}^{-})-1$ (characterizing leptonic…
