A precise determination of the W boson mass at the Fermilab Tevatron requires a theoretical calculation in which the effects of the initial-state multiple soft-gluon emission and the final-state photonic correction are simultaneously included. Here, we present such a calculation and discuss its prediction on the transverse mass distribution of the W boson and the transverse momentum distribution of its decay charged lepton, which are the most relevant observables for measuring the W boson mass at hadron colliders.
要在费米实验室的万亿电子伏特加速器（Tevatron）上精确测定W玻色子的质量，需要进行一项理论计算，其中要同时考虑初态多软胶子发射和末态光子修正的影响。在此，我们给出这样一项计算，并讨论其对W玻色子横向质量分布及其衰变带电轻子横向动量分布的预测，这两者是强子对撞机上测量W玻色子质量最相关的可观测量。
