摘要：

This Next-to-Leading Order (NLO) Quantum Chromo Dynamics (QCD) analysis attempts to investigate the impact of LHCb charm and beauty production data in pp collisions at root s = 7 TeV on the Parton Distribution Functions (PDFs) extracted from H1 and ZEUS collaboration data sets. We show adding the LHCb charm and beauty production data on the HI and ZEUS combined data sets reduces the uncertainty bands of partonic distributions and improve the relative fit-quality up to 4.0 %.
