论文摘要
我们提出了一项新的分析,以在统计模型的框架内提取Pion Parton分布功能(PDF)。从最初为Spin-1/2核子开发的统计模型开始,我们扩展了该模型以描述Spin-0 Pion。基于与Pion诱导的Drell-Yan数据和Pion诱导的$ J/ψ$生产数据的组合拟合,已经获得了一组新的PION PDFS。将$ j/ψ$生产数据纳入合并拟合中,为更好地确定Pion中的Gluon分布提供了其他约束。我们还将统计模型中获得的PDF与其他现有的PION PDF进行了比较。
We present a new analysis to extract pion parton distribution functions (PDFs) within the framework of the statistical model. Starting from the statistical model first developed for the spin-1/2 nucleon, we extend this model to describe the spin-0 pion. Based on a combined fit to both the pion-induced Drell-Yan data and the pion-induced $J/Ψ$ production data, a new set of pion PDFs has been obtained. The inclusion of the $J/Ψ$ production data in the combined fit has provided additional constraints for better determining the gluon distribution in the pion. We also compare the pion PDFs obtained in the statistical model with other existing pion PDFs.
