    <description descriptionType="Abstract">&lt;p&gt;Measurements of the associated production of a W boson and a charm (    $\text{c}$  ) quark in proton–proton collisions at a centre-of-mass energy of 8    $\phantom{\rule{0.166667em}{0ex}}\text{TeV}$   are reported. The analysis uses a data sample corresponding to a total integrated luminosity of 19.7    $\phantom{\rule{0.166667em}{0ex}}{\text{fb}}^{-1}$   collected by the CMS detector at the LHC. The W bosons are identified through their leptonic decays to an electron or a muon, and a neutrino. Charm quark jets are selected using distinctive signatures of charm hadron decays. The product of the cross section and branching fraction     $\sigma \left(\text{pp}\to \text{W}+\text{c}+\text{X}\right)B\left(\text{W}\to \ell \nu \right)$  , where     $\ell =\text{e}$   or     $\mu $  , and the cross section ratio     $\sigma \left(\text{pp}\to {\text{W}}^{+}+\overline{\text{c}}+\text{X}\right)/\sigma \left(\text{pp}\to {\text{W}}^{-}+\text{c}+\text{X}\right)$   are measured in a fiducial volume and differentially as functions of the pseudorapidity and of the transverse momentum of the lepton from the W boson decay. The results are compared with theoretical predictions. The impact of these measurements on the determination of the strange quark distribution is assessed.&lt;/p&gt;</description>
