在PDMATHAAC PDKEEPAAAAD使用PDKEEPAAAAE运行PDKEEPAAAAF全部数据集在PDMATHAAB碰撞中与$W$玻色子有关产生的喷流对的不变质量分布

Invariant-mass distribution of jet pairs produced in association with a $W$ boson in \ppbar collisions at $\sqrt{s}=1.96$ TeV using the full CDF Run II data set

T. Aaltonen

摘要:

我们报告一个确定的轻子,一个显着的不平衡,在总事件的横向动量,和两个喷流的事件中的dijet不变质量分布的研究。这种分布对可能产生的与$W$玻色子相关的新粒子很敏感,在那里玻色子以轻子方式衰变。我们使用完整的数据集的质子-反质子碰撞在1.96 TeV的质量中心的能量收集的对撞机探测器在费米实验室Tevatron和对应的积分亮度为8.9 FB $^{-1}$。的数据被发现是与标准模型的预期一致,和一个95 $\%$置信水平的上限被设置在横截面上的$W$玻色子与一个新的粒子衰变成两个射流。

英文摘要:

We report on a study of the dijet invariant-mass distribution in events with one identified lepton, a significant imbalance in the total event transverse momentum, and two jets. This distribution is sensitive to the possible production of a new particle in association with a $W$ boson, where the boson decays leptonically. We use the full data set of proton-antiproton collisions at 1.96 TeV center-of-mass energy collected by the Collider Detector at the Fermilab Tevatron and corresponding to an integrated luminosity of 8.9 fb$^{-1}$. The data are found to be consistent with standard-model expectations, and a 95$\%$ confidence level upper limit is set on the cross section for a $W$ boson produced in association with a new particle decaying into two jets.
