Production cross section of electrons from W$^{-}$ (left) and positrons from W$^{+}$ (right) decays at midrapidity in pp collisions at $\sqrt{s}=$13 {\TeV}, compared with POWHEG calculations with the CT14NNLO , CT18NLO  and NNPDF4.0  PDF sets. The production cross sections are obtained by integrating e$^{\pm} \leftarrow \textrm{W}^{\pm}$ in the interval $30 p_{\rm T} 60$  GeV/$c$. Statistical and systematic uncertainties of the measurement are shown as a vertical line and an open box, respectively.
