Measurements at \(\sqrt{s}=240\) GeV

At \(\sqrt{s}=240\) GeV, the TLEP luminosity is expected to be \(5\times 10^{34}~{}{\rm cm}^{-2}{\rm s}^{-1}\) at each interaction point, in a configuration with four IPs. The total integrated luminosity accumulated in five years, assuming running for \(10^{7}\) seconds per year, is shown in Table \ref{tab:HiggsCross}, together with the corresponding numbers of Higgs bosons produced.

\label{tab:HiggsCross}Integrated luminosity and number of Higgs bosons produced with TLEP at \(\sqrt{s}=240\) GeV (summed over four IPs), for the Higgs-strahlung process and the WW fusion. For illustration, the corresponding numbers are also shown for the baseline ILC programme —\cite{ILC:Summary}— at \(\sqrt{s}=250\) GeV, with beams polarized at a level of 80% for electrons and 30% for positrons.
