1  AABOUD 2018J select 4.61M ${{\mathit W}^{+}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$, 3.40M ${{\mathit W}^{+}}$ $\rightarrow$ ${{\mathit e}^{+}}{{\mathit \nu}_{{{e}}}}$, 3.23M ${{\mathit W}^{-}}$ $\rightarrow$ ${{\mathit \mu}^{-}}{{\overline{\mathit \nu}}_{{{\mu}}}}$ and 2.49M ${{\mathit W}^{-}}$ $\rightarrow$ ${{\mathit e}^{-}}{{\overline{\mathit \nu}}_{{{e}}}}$ events in 4.6 fb${}^{-1}{{\mathit p}}{{\mathit p}}$ data at 7 TeV. The ${{\mathit W}}$ mass is determined using the transverse mass and transverse lepton momentum distributions, accounting for correlations. The systematic error includes 0.007 GeV experimental and 0.024 GeV modelling uncertainties.
