It is concluded that if 500 fb$^{-1}$ is delivered to the experiment, $Δ(\MXN{1}) = 920 \MeVcc$, $Δ(\msmul) = 100 \MeVcc$, $Δ(\MXN{2}) = 1.38 ~\GeVcc$, and $Δ(σ(\eeto \smul \smul))$ = 1.35 fb can be achieved from the $μ$ channels alone. The preliminary results from the $\stau$ channels, indicates that $Δ(P_τ) = 13 $ % is also achievable.High Energy Physics - Experimenttext
