从半包容深度非弹性散射和Drell-Yan数据提取部分子横向动量分布

Extraction of partonic transverse momentum distributions from semi-inclusive deep inelastic scattering and Drell-Yan data

Cristian Pisano, Alessandro Bacchetta, Filippo Delcarro, Marco Radici, Andrea Signori

摘要:

我们提出了第一次尝试在全球拟合的非极化夸克的横向动量依赖的分布和碎裂功能的半包容性深非弹性散射,Drell-Yan和$Z$玻色子生产过程的可用数据。这种分析是在低横向动量区域,在微扰QCD的领导阶,并列入下一个领先的对数精度的能量标度演化的影响。

英文摘要:

We present a first attempt at a global fit of unpolarized quark transverse momentum dependent distribution and fragmentation functions from available data on semi-inclusive deep-inelastic scattering, Drell-Yan and $Z$ boson production processes. This analysis is performed in the low transverse momentum region, at leading order in perturbative QCD and with the inclusion of energy scale evolution effects at the next-to-leading logarithmic accuracy.
