用ATLAS实验研究sqrt(s)=7 TeV质子-质子碰撞中喷流的产生

Jet Production in proton-proton collisions at sqrt(s) =7 TeV with the ATLAS experiment

C. Roda

摘要:

我们报告的第一次测量所做的ATLAS实验的质子-质子碰撞中产生的高能射流的特性在质心能量为7 TeV。使用距离参数R=0.6的反kt聚类算法重建射流。本文所研究的运动学区域对应于横向动量p_T>30$GeV的快度喷流|Y型喷气发动机|<2.8。一个关键的了解射流生产的数据进行比较,预测的基础上领先阶QCD矩阵元素加上部分子簇射蒙特卡罗模拟事件。所示结果是在对应于大型强子对撞机提供的约1 nb**-1的积分亮度的数据样本上获得的。

英文摘要:

We report on the first measurements done with the ATLAS experiment of the characteristics of energetic jets produced in proton-proton collisions at the center of mass energy of 7 TeV. Jets are reconstructed using the anti-kt clustering algorithm with distance parameter R=0.6. The kinematic region investigated in this paper corresponds to jets with transverse momentum p_T>30$GeV and rapidity |y_jet |<2.8. A critical understanding of the jet production is obtained by comparing the data to predictions based on leading-order QCD matrix elements plus parton shower Monte Carlo simulated events. The results shown are obtained on a data sample corresponding to about 1 nb**-1 of integrated luminosity delivered by the Large Hadron Collider.
