给出了用ATLAS探测器在质子-质子碰撞中产生与反子有关的粒子喷流的结果。分析包括2010年的完整数据集，这些数据集是在加速器中多次质子-质子碰撞的低比率下收集的，对应于综合光度。对于具有横向动量和喷流速度的喷注，测量了衰变为电子对或µ子对的事件中包含的喷注截面。这些测量值与次导数阶微扰QCD计算、<；？格式？>；以及来自不同蒙特卡罗生成器的预测进行了比较，这些蒙特卡罗生成器实现了由部分子簇射补充的先导阶矩阵元。
Results are presented on the production of jets of particles in association with aboson, in proton-proton collisions atwith the ATLAS detector. The analysis includes the full 2010 data set, collected with a low rate of multiple proton-proton collisions in the accelerator, corresponding to an integrated luminosity of. Inclusive jet cross sections inevents, withdecaying into electron or muon pairs, are measured for jets with transverse momentumand jet rapidity. The measurements are compared to next-to-leading-order perturbative QCD calculations, <?format ?>and to predictions from different Monte Carlo generators implementing leading-order matrix elements supplemented by parton showers.
