\begin{equation}  \Gamma_{\rm tot} = { {\Gamma {\rm(H \to ZZ)}} \over {{\rm BR(H \to ZZ)}} }.  \end{equation}  The partial decay width $\Gamma{\rm(H \to ZZ)}$ is directly proportional to the inclusive cross section $\sigma_{\rm HZ}$ (measured with excellent precision of 0.4\% from the ``recoil mass'' distribution of Fig.~\ref{fig:Recoil}). The Higgs boson branching ratio to ZZ is in turn obtained from the number of ZZZ events, itself proportional to $\sigma_{\rm HZ} \times {\rm BR(H\to ZZ)}$, measured with a 3.1\% relative precision. With the sole 240 GeV data, TLEP is therefore able to determine the Higgs boson decay width with a precision of the order of 3\% in from  this channel. The ${\rm H \to b\bar b}\nu\bar\nu$ final state produced via WW fusion can also be used for that purpose, as described in more details in the next section.
