Abstract

We have measured the mass of the Z boson to be 91.11\ifmmode\pm\else\textpm\fi{}0.23 GeV/${c}^{2}$, and its width to be ${1.61}_{\mathrm{\ensuremath{-}}0.43}^{+0.60}$ GeV. If we constrain the visible width to its standard-model value, we find the partial width to invisible decay modes to be 0.62\ifmmode\pm\else\textpm\fi{}0.23 GeV, corresponding to 3.8\ifmmode\pm\else\textpm\fi{}1.4 neutrino species.
