论文摘要
我们使用与Fermilab Tevatron Collider在$ \ \ sqrt {s sqrt {s} = 1.96 $ tev一起收集的$ p \ bar p $碰撞的$ W $玻色子的标准化横向动量分布，该研究的$ w $ bosons的标准化横向动量分布。该测量集中在15 GEV以下的横向动量区域，这对于Electroweak精确测量特别感兴趣。它依赖于相同的检测器校准方法，用于精确测量$ W $玻色子质量。将测量的分布与不同的QCD预测进行了比较，并给出了一个程序，以允许将任何进一步的理论模型与D0数据进行比较。
We present a study of the normalized transverse momentum distribution of $W$ bosons produced in $p \bar p$ collisions, using data corresponding to an integrated luminosity of 4.35 fb$^{-1}$ collected with the D0 detector at the Fermilab Tevatron collider at $\sqrt{s}=1.96$ TeV. The measurement focuses on the transverse momentum region below 15 GeV, which is of special interest for electroweak precision measurements; it relies on the same detector calibration methods which were used for the precision measurement of the $W$ boson mass. The measured distribution is compared to different QCD predictions and a procedure is given to allow the comparison of any further theoretical models to the D0 data.
