The additional events from the Higgs-strahlung process allow the statistical precision for all the aforementioned measurements to be improved by typically 10\% for TLEP, and by about 40\% for the ILC. The large number of Higgs bosons produced by boson fusion allows, in both colliders, a measurement of the total width in the ${\rm b\bar b}\nu\bar\nu$ final state. Both the Higgs-strahlung process (when the Z decays to a neutrino pair) and the WW fusion process contribute to this final state, when the Higgs boson decays to ${\rm b \bar b}$, with a similar cross section. The mass recoiling to the ${\rm b \bar b}$ system, however, peaks around $m_{\rm Z}$ for the Higgs-strahlung and clusters below $\sqrt{s}-m_{\rm H}$ for the WW fusion. The distribution of this invisible recoil mass is shown in Fig.~\ref{fig:wwfusion}, as obtained from Ref.~\cite{cite:durig}.
