\subsection{Higgs physics in $\epem$ collisions at $\sqrt{s} = 500$~GeV}  With a luminosity (slightly) larger than ILC and CLIC at $\sqrt{s}=500$~GeV, the TLEP physics potential at this centre-of-mass energy would be similar to that of linear colliders. A quick look at the The  ILC TDR~\cite{cite:ILCTDR} shows that the addition of 500~$\infb$ at 500~GeV to the baseline programme with 250~$\infb$ at 250~GeV and 350~$\infb$ at 350 GeV moderately improves the precision on all Higgs boson couplings to light fermions and gauge bosons by less than a factor $\sqrt{2}$, still quite far from the needed sub-per-cent precision. Similarly, the measurement of the invisible width of the Higgs boson is best performed at $\sqrt{s}=$ 240~GeV. The opening of the $\epemto \ttbar{\rm H}$ process also allows the Htt coupling to be directly measured, typically with a precision of 14\% at ILC, and 10\% at TLEP. The improvement with respect to the TLEP measurement at the $\ttbar$ threshold, with an accuracy of 13\% is marginal. More importantly, these precisions are not competitive with the HL-LHC projections~\cite{1307.7135,1307.7292}. For example, the CMS collaboration would be able to measure the Htt coupling to 7\% with the sole ${\rm H} \to \bbbar, \gamma\gamma$ decay channels and an integrated luminosity of 3~$\inab$. This precision is improved to 5\% with the combination of the two LHC experiments, and to significantly better when the ${\rm H} \to \tau\tau$, ZZ, and WW leptonic decay channels are added.
