\subsection{Measurements with TeraZ}  With a continuous luminosity of $5\times 10^{35} \cms$ per IP at a centre-of-mass of 90 GeV, TLEP is a Z-factory able to deliver $7\times 10^{11}$ visible Z decays per year, for one year of running,  with very clean experimental conditions, centre-of-mass energy known to a fraction of MeV and the possibility of longitudinally polarized beams. This allows the following experiments to be carried out. \begin{itemize}  \item   A precise scan of the Z resonance allowing precise determination of the Z mass and width; 
...
\item   Data taking with longitudinally polarized beams.   \end{itemize}  An extensive description of Electroweak measurements performed at LEP and SLC in 1988-1998 can be found in~\cite{ements_on_the_Z_resonance_2006}. It is beyond the scope of this article to revisit all the measurements to establish the improvements brought about by TLEP, and we limit ourselves to a few key measurements. The typical improvement in statistics over the LEP experiments being a factor $10^5$ (a factor 300 reduction in statistical errors!) it is clear that a detailed consideration of systematic errors will be essential before a precise conclusion will be drawn on the achievable precisions. In addition, uncertainties in the theoretical interpretation will need to be revisited, this implying a significant new program of calculations of higher order Electroweak corrections.  The Z mass and width
