首次用ATLAS探测器测量了质心能量为7 TeV的质子-质子碰撞中的喷流截面。该测量使用大型强子对撞机记录的17 nb− 1的积分光度。反kt算法用于识别射流，具有两个射流分辨率参数，R= 0.4和0.6。占主导地位的不确定性来自喷流的能量尺度，它被确定为在7%的中央喷流超过60 GeV的横向动量。包含单射流微分截面作为射流横向动量和速度的函数。双射流截面是双射流质量和角度变量χ的函数。结果进行了比较，预期的基础上下一个领先阶QCD，同意的数据，提供了一个新的运动学制度的理论验证。
Jet cross sections have been measured for the first time in proton-proton collisions at a centreof-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb− 1 recorded at the Large Hadron Collider. The anti-kt algorithm is used to identify jets, with two jet resolution parameters, R= 0.4 and 0.6. The dominant uncertainty comes from the jet energy scale, which is determined to within 7% for central jets above 60 GeV transverse momentum. Inclusive single-jet differential cross sections are presented as functions of jet transverse momentum and rapidity. Dijet cross sections are presented as functions of dijet mass and the angular variable χ. The results are compared to expectations based on next-to-leading-order QCD, which agree with the data, providing a validation of the theory in a new kinematic regime.
