Summary of ILD performance at SPS1a'

The performance of the ILD detector at the ILC for the analysis of $\mu$ and $\tau$ channels at the SUSY benchmark-point SPS1a’ has been studied with full detector simulation. It is concluded that if 500 fb${}^{-1}$ is delivered to the experiment, $\mathrm{\Delta }(\text{MXN}1)=920\text{MeVcc}$, $\mathrm{\Delta }(\text{msmul})=100\text{MeVcc}$, $\mathrm{\Delta }(\text{MXN}2)=1.38\text{GeVcc}$, and $\mathrm{\Delta }(\sigma (\text{eeto}\text{smul}\text{smul}))$ = 1.35 fb can be achieved from the $\mu$ channels alone. The preliminary results from the $\text{stau}$ channels, indicates that $\mathrm{\Delta }(P_{\tau })=13$ % is also achievable.
