Table 13.

The values of the total $W+c$ cross section (in pb), and the $W^{+}/W^{-}$ ratio $R_c^{\pm }$, measured by CMS [144], compared with the predictions obtained using MSTW2008 and MMHT2014 NLO PDFs. The charm jet is subject to the acceptance cuts $p_T^{\mathrm{jet}}>25$ GeV and $|{\mathit{\eta }}^{\mathrm{jet}}|<2.5$
