In this paper, we present a CT18 PDF global QCD analysis at leading order in QCD perturbation theory. The CT18 LO PDFs is obtained within the general CT18 framework, along with two additional procedures imposed to improve the quality of the fit. We take the W-boson charge asymmetry and inclusive single-top production at LHC as examples to illustrate implications of the CT18 LO PDFs.
