标题： New results in the CTEQ-TEA global analysis of parton distributions in the nucleon

摘要： 这份报告总结了CTEQ-TEA在核子部分子分布函数(PDFs)全球分析中的最新进展。重点是针对8 TeV和13 TeV高精度LHC数据的最近NNLO拟合，包括Drell-Yan、喷注和顶夸克对产生，这是为发布新一代CTEQ-TEA通用PDFs所做的努力。报告还讨论了PDF确定和不确定性量化方面的统计和数值方法进展，强调了对于高风险可观测量的稳健和可重复不确定性的重要性。此外，还涵盖了与PDF确定相关的现象学研究，例如实验约束之间的相互作用，高-$x$核子海与低能宇称破坏测量之间的相关性探索，核子中拟合的魅夸克，中子中的光子PDF，以及同时进行的SMEFT-PDF分析。 显示英文摘要

摘要： This report summarizes the latest developments in the CTEQ-TEA global analysis of parton distribution functions (PDFs) in the nucleon. The focus is on recent NNLO fits to high-precision LHC data at 8 and 13 TeV, including Drell-Yan, jet, and top-quark pair production, pursued on the way toward the release of the new generation of CTEQ-TEA general-purpose PDFs. The report also discusses advancements in statistical and numerical methods for PDF determination and uncertainty quantification, highlighting the importance of robust and replicable uncertainties for high-stakes observables. Additionally, it covers phenomenological studies related to PDF determination, such as the interplay of experimental constraints, exploration of correlations between high-$x$ nucleon sea and low-energy parity-violating measurements, fitted charm in the nucleon, the photon PDF in the neutron, and simultaneous SMEFT-PDF analyses.
