Measured boson charge asymmetry, after folding, compared to predictions and the CDF result. The points show the measured asymmetry, with the horizontal bars delineating the statistical uncertainty component and the vertical lines showing the total uncertainty. The central value and uncertainty from mc@nlo [3] using the nnpdf2.3 [4] PDF sets and the predictions from resbos [5] using the CTEQ6.6 [6] central PDF set and mc@nlo using the MSTW2008NLO [7] central PDF set are also shown. The inset focuses on the region from 0 to 1.5.
