英文摘要	We calculate cross-sections and cross-section ratios of a charm quark production in association with a W gauge boson at next-to-leading order QCD using MadGraph and CT10NNLO, CT14NNLO, and MSTW2008NNLO PDFs. We compare the results with measurements from the CMS detector at the LHC at a center-of-mass energy of 7 TeV. Moreover, we calculate absolute and normalized differential cross-sections as well as differential cross-section ratios as a function of the lepton pseudorapidity from the W boson decay. The correlation between the CT14NNLO PDFs and predictions for charm data are studied as well. Furthermore, by employing the error PDF updating method proposed by charm production data to the original CT14NNLO PDFs. By comparison of the GeV for the CT14NNLO and CT14NNLO+Wc, we see that the error band of the PDF is reduced in the region and the error band of PDF is also slightly reduced at region 0.01 < x < 0.1.
