标题： xFitter Updates: Probing Z Boson Couplings with Forward-Backward Asymmetry

摘要： 我们介绍了xFitter软件框架在高能物理中部分子分布函数全局拟合方面的最新更新。 我们的重点是通过Drell-Yan产生中的前后不对称性来研究对Z玻色子耦合的敏感性。 通过使用一种有效的方法和模拟数据，我们评估了这些耦合的准确性，特别是考虑到完整的LHC数据样本。 此外，我们将结果与未来对撞机的预测进行比较，提供了它们在理解Z玻色子相互作用方面潜在影响的见解。 显示英文摘要

摘要： We present recent updates in the xFitter software framework for global fits of parton distribution functions in high-energy physics. Our focus is on investigating the sensitivity to Z boson couplings using the forward-backward asymmetry in Drell-Yan production. By utilizing an effective approach and simulated data, we assess the accuracy of these couplings, specifically considering the full LHC data sample. Furthermore, we compare our results with predictions for future colliders, providing insights into their potential impact on understanding Z boson interactions.
