论文摘要
横向动量依赖分布(TMD)是载体玻色子产生中分解定理的重要组成部分。它们是非扰动,双重依赖性函数,渐近地匹配共线parton分布函数(PDF)。一旦使用PDF表示TMD,就会观察到它们对PDF集的选择和质量(PDF偏置)敏感。找到并讨论了解决此问题的解决方案。然而,矢量玻色子光谱的主要错误来源仍然来自PDF不确定性传播。
The transverse momentum dependent distributions (TMD) are an essential part of the factorization theorems in vector boson production. They are non-perturbative, double scale dependent functions that asymptotically match onto collinear parton distributions functions (PDF). Once TMD are expressed using PDF, one observes that they are sensitive to the choice and quality of PDF sets (PDF bias). A solution to this problem is found and discussed. Nevertheless the main source of error on vector boson spectra still comes from PDF uncertainty propagation.
