论文摘要
在强子围墙上，可以分解$ W $生产的差分横截面，并且对于低玻色子横向动量，它是敏感的横向动量依赖分布（TMD）。虽然通常会将相应的非扰动QCD贡献推断出从$ z $玻色子的产量中推断出来，但在这里，我们使用TMD的现有提取（基于Artemide）的现有提取（基于Artemide），其中包括来自Drell-Yan和半包含深度弹性散射的数据，以提供$ W $案例的检查和预测。包括具有不同构型和运动功率校正的基准切割，我们考虑在矢量玻色子横向质量的几个间隔内横向相关的横截面。我们对$ p_t^{w^ - }/p_t^{w^+} $和$ p_t^z/p_t^w $发行$进行同一研究。我们将我们的预测与Atlas和CMS的这些数量的最新提取以及Tevatron的结果进行了比较。结果鼓励了更广泛的实验和现象学工作，并为$ w $案例进行了更深入的TMD研究。
At hadron colliders, the differential cross section for $W$ production can be factorized and it is sensitive transverse momentum dependent distributions (TMD) for low boson transverse momentum. While, often, the corresponding non-perturbative QCD contributions are extrapolated from $Z$ boson production, here we use an existing extraction (based on the code Artemide) of TMD which includes data coming from Drell-Yan and semi-inclusive deep inelastic scattering, to provide checks and predictions for the $W$ case. Including fiducial cuts with different configurations and kinematical power corrections, we consider transverse momentum dependent cross sections within several intervals of the vector boson transverse mass. We perform the same study for the $p_T^{W^-}/p_T^{W^+}$ and $p_T^Z/p_T^W$ distributions. We compare our predictions with recent extractions of these quantities at ATLAS and CMS and results from TeVatron. The results encourage a broader experimental and phenomenological work, and a deeper study of TMD for the $W$ case.
