论文摘要
我们使用Xfitter（一个开源QCD FIT框架，用于促进PDF提取和分析的开源QCD FIT框架，我们介绍了带电Pions的Parton分布函数（PDF）的第一个开源分析。我们的计算是使用MCFM Generator生成的applgrid以近代领先顺序（NLO）实施的。使用当前可用的Drell-Yan和Photon生产数据，我们发现价分布受到限制。但是，所考虑的数据不足以明确确定海洋和gluon分布。讨论了价值，海洋和Gluon组件所携带的动量的分数，我们将果酱协作和GRV组的结果进行比较。
We present the first open-source analysis of parton distribution functions (PDFs) of charged pions using xFitter, an open-source QCD fit framework to facilitate PDF extraction and analyses. Our calculations are implemented at next-to-leading order (NLO) using APPLgrids generated by MCFM generator. Using currently available Drell-Yan and photon production data, we find the valence distribution is well constrained; however, the considered data are not sensitive enough to unambiguously determine sea and gluon distributions. Fractions of momentum carried by the valence, sea and gluon components are discussed, and we compare with the results of JAM collaboration and the GRV group.
