The \MET distributions for the selected \PWpen~(upper) and \PWpmn~(lower) candidates for $ 17.5 < \ptW < 24$\GeV (left) and the corresponding QCD multijet-enriched control sample (right). Solid lines represent the results of the fit. The dotted lines represent the signal shape after background subtraction. The bottom panels show the difference between data and fitted results divided by the statistical uncertainty in data, $\sigma_\text{Data}$.

Signal and background yields after fitting the data for \PWpen~(upper left), \PWmen~(upper right), \PWpmn~(lower left), and \PWmmn~(lower right) as a function of the $\PW$ boson \pt. The points are data yields with statistical uncertainties. The stacked histogram shows the signal and background components estimated from a fit to the \MET or \MT~ distribution at each $\PW$ boson \pt bin.

Data and simulated events for both DY processes and various backgrounds after event reconstruction. Left (right): events for low (high) $\ptZ$, {$\ptZ< 30~(\geq 30)\GeV$}. The lower panels show the difference between the data and the simulation predictions divided by the statistical uncertainty in data, $\sigma_\text{Data}$.

Normalized differential cross sections for charge independent $\PW$ boson production at the lepton pre-FSR level as a function of $\ptW$ for electron (upper) and muon (lower) decay channels. The right panels show the ratios of theory predictions to the data. The bands include (i) the statistical uncertainties, uncertainties from scales, and PDF uncertainties for FEWZ; (ii) the statistical uncertainties and PDF uncertainties for POWHEG; (iii) the uncertainty from scales for \textsc{ResBos}-P; and (iv) the sum of the statistical and systematic uncertainties in quadrature for data.

Comparison of the normalized dimuon differential transverse momentum distribution from data (solid symbols) with different theoretical predictions. The right panels show the ratios of theory predictions to the data. The \textsc{ResBos}-CP version with scale and PDF variation is used for comparison.

The normalized $\pt$ differential cross section ratio of $\Z$ to $\PW$ for muon channel compared with theoretical predictions. The right panels show the ratios of theory predictions to the data. The larger than expected uncertainties for \textsc{ResBos} arise from the different strategies in terms of the scale and PDF variations between \textsc{ResBos}-P and \textsc{ResBos}-CP version. More details are given in the Fig.~\ref{fig:Wincl_result} and \ref{fig:ZpTcombo} caption.
