$\sqrt{s}=1.96$ TeV的$W$玻色子的归一化横动量分布研究

Study of the normalized transverse momentum distribution of $W$ bosons produced in $p \bar p$ collisions at $\sqrt{s}=1.96$ TeV

D0 Collaboration

摘要:

本文利用费米实验室Tevatron对撞机D 0探测器收集的4.35 fb $^{-1}$的积分亮度数据,研究了$W$玻色子在$\sqrt{s}=1.96$ TeV下的归一化横向动量分布。测量的重点是低于15 GeV的横向动量区域,这是特别感兴趣的电弱精密测量;它依赖于相同的检测器校准方法,用于精确测量的$W$玻色子质量。测得的分布进行比较,不同的QCD预测和程序给出的任何进一步的理论模型的D 0数据进行比较。

英文摘要:

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.
