论文摘要
我们提供Xfitter开源软件包的概述，查看程序的一般功能，并突出显示与雪人研究有关的应用程序。该程序的更新版本（2.2.0）可在Cern Gitlab上获得，并且已将其更新为具有增强和扩展功能的C ++代码库。我们还讨论了可能对精确研究有用的一些正在进行的和未来的代码发展。我们调查了XFITTER开发人员团队进行的最新分析，包括：W和Z生产，光子PDF，Drell-Yan向前的不对称研究，对小X贡献的重新介绍，重型夸克的产生，对奇怪的PDF的限制，对PDF的确定以及PION Fragmentation的确定。最后，我们简要总结了文献中Xfitter的选定应用程序。 Xfitter计划是一种多功能，灵活，模块化和全面的工具，可以为可能的未来设施提供影响研究。我们鼓励使用Xfitter，并欢迎社区的新贡献。
We provide an overview of the xFitter open-source software package, review the general capabilities of the program, and highlight applications relevant to the Snowmass study. An updated version of the program (2.2.0) is available on CERN GitLab, a and this has been updated to a C++ codebase with enhanced and extended features. We also discuss some of the ongoing and future code developments that may be useful for precision studies. We survey recent analyses performed by the xFitter developers' team including: W and Z production, photon PDFs, Drell-Yan forward-backward asymmetry studies, resummation of small-x contributions, heavy quark production, constraints on the strange PDF, determination of the pion PDF, and determination of the pion Fragmentation Functions. Finally, we briefly summarize selected applications of xFitter in the literature. The xFitter program is a versatile, flexible, modular, and comprehensive tool that can provide impact studies for possible future facilities. We encourage the use of xFitter, and welcome new contributions from the community.
