\begin{document}$W+$\end{document} charm data are studied as well. Furthermore, by employing the error PDF updating method proposed by the CTEQ-TEA group, we update CT14NNLO PDFs, and analyze the impact of CMS 7 TeV \begin{document}$W+$\end{document} charm production data to the original CT14NNLO PDFs. By comparison of the \begin{document}$g(x,Q)$\end{document}, \begin{document}$s(x,Q)$\end{document}, \begin{document}$u(x,Q)$\end{document}, \begin{document}$d(x,Q)$\end{document}, \begin{document}$\bar u(x,Q)$\end{document}, and \begin{document}$\bar d(x,Q)$\end{document} PDFs at \begin{document}$Q=1.3$\end{document} GeV and \begin{document}$Q = 100$\end{document} GeV for the CT14NNLO and CT14NNLO+Wc, we see that the error band of the \begin{document}$s(x,Q)$\end{document} PDF is reduced in the region \begin{document}$x<0.4$\end{document}, and the error band of \begin{document}$g(x,Q)$\end{document} PDF is also slightly reduced at region \begin{document}$0.01 < x<0.1$\end{document}."> QCD analysis of CMS <i>W</i> + charm measurements at LHC with <inline-formula><tex-math id="M2">\begin{document}${\sqrt { s} = 7\; {\bf{TeV}}}$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/b93c70ad-3288-4238-bde9-e93e805bd747/CPC-2019-0268_M2.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/b93c70ad-3288-4238-bde9-e93e805bd747/CPC-2019-0268_M2.png"/></alternatives></inline-formula> and implications for strange PDF -
