\subsection{Measurements with TeraZ}  With a continuous luminosity of $5\times $5.6\times  10^{35} \cms$ per IP at a centre-of-mass of 91 GeV, TLEP is a Z factory able to deliver over $20~\inab$ of data, i.e.,  $7\times 10^{11}$ visible Z decays for one year of running (hence the ``Tera Z'' appellation), with very clean experimental conditions, centre-of-mass energy known to a fraction of MeV, and the possibility of longitudinally polarized beams, with which the following experiments can be carried out: \begin{itemize}  \item a high-statistics line-shape scan of the Z resonance, allowing a precise determination of the Z mass and width;  \item high statistics data collection at the Z peak, towards the measurement of the Z partial widths, the determination of the number of light neutrinos, and the detection of rare decays;
