标题： Status and Developments in Polarised Parton Distribution Functions

摘要： 准确且精确的极化部分子分布函数（PDFs）的需求在即将到来的几年内计划进行的电子-离子对撞机实验项目中变得越来越重要。最近已经提出了两种在下一阶下一阶精度下的全球PDF确定方法，即MAPPDFpol1.0和BDSSV24。我将回顾前者，并提供与其他达到下一阶精度的PDF集的比较讨论。我表明，这些PDF集之间的差异，由于实验和方法输入的选择，超过了微扰精度带来的差异。 显示英文摘要

摘要： The need for accurate and precise polarised parton distribution functions (PDFs) is becoming increasingly crucial in view of the Electron-Ion Collider experimental program foreseen in the coming years. Two global PDF determinations at next-to-next-to-leading order accuracy have been recently presented, MAPPDFpol1.0 and BDSSV24. I review the former and I provide a comparative discussion of other PDF sets accurate to next-to-leading order. I show that differences between these PDF sets, due to the choice of experimental and methodological input, exceed differences due to perturbative accuracy.
