Number of observed candidates N, of expected background events B, and the correction factors C for the $W^{+}$, $W^{-}$, and $Z/{\mathit{\gamma }}^{\ast }$ ($66<m_{\mathit{\mu }\mathit{\mu }}<116\text{GeV}$) muon channels. The correction factors C were defined in Eq. (6). The charge asymmetry in the background to the $W^{\pm }$ channels stems from the $W\to \mathit{\tau }\mathit{\nu }$ contributions, which is proportional to the signal yield. The uncertainties are the quadratic sum of statistical and systematic components. The statistical uncertainties in C are negligible
