Table 10.

Ratios of total CC and NC cross sections obtained from the combination of electron and muon channels with statistical and systematic uncertainties. The $Z/{\mathit{\gamma }}^{\ast }$ cross section is defined for the dilepton mass window $66<m_{\ell \ell }<116\text{GeV}$. The uncertainties denote the statistical (stat), the experimental systematic (syst), the luminosity (lumi), and acceptance extrapolation (acc) contributions

$R_{W^{+}/W^{-}}^{\mathrm{tot}}$	$1.450\pm 0.001(\mathrm{stat})\pm 0.004(\mathrm{syst})\pm 0.029(\mathrm{acc})$
$R_{W/Z}^{\mathrm{tot}}$	$10.83\pm 0.01(\mathrm{stat})\pm 0.05(\mathrm{syst})\pm 0.09(\mathrm{acc})$
$R_{W^{+}/Z}^{\mathrm{tot}}$	$6.407\pm 0.004(\mathrm{stat})\pm 0.032(\mathrm{syst})\pm 0.062(\mathrm{acc})$
$R_{W^{-}/Z}^{\mathrm{tot}}$	$4.419\pm 0.003(\mathrm{stat})\pm 0.024(\mathrm{syst})\pm 0.082(\mathrm{acc})$
