Fig. 9.

Normalised differential cross sections for the sum of $t\text{-channel}$ single top quark and antiquark production at the parton level: (upper row) top quark $p_{\mathrm{T}}$ and rapidity; (middle row) charged lepton $p_{\mathrm{T}}$ and rapidity; (lower left) $\text{W}$  boson $p_{\mathrm{T}}$; (lower right) cosine of the top quark polarisation angle. The total uncertainty is indicated by the vertical lines, while horizontal bars indicate the statistical and experimental uncertainties, which have been profiled in the ML fit, and thus exclude the uncertainties in the theoretical modelling. Three different predictions from event generators are shown by the solid, dashed, and dotted lines. The lower panels show the ratios of the predictions to the data
