在大型强子对撞机上用ATLAS探测器测量了TeV质子-质子碰撞中产生至少四个喷流的微分截面。如果在快度范围内具有最大横向动量（pT）的四个反ktR = 0.4喷流，则选择事件|y| < 2.8的喷流分离良好（ΔR min 4j> 0.65），它们的p T> 64 GeV，并且至少包含一个p T> 100 GeV的喷流。该数据集对应的积分光度为20.3 fb− 1。的横截面，校正检测器的影响，比较领先的顺序和下一个领先的顺序计算作为一个函数的射流动量，不变的质量，最小和最大的开角和其他运动学变量。
Differential cross sections for the production of at least four jets have been measured in proton-proton collisions atTeV at the Large Hadron Collider using the ATLAS detector. Events are selected if the four anti-k t R= 0.4 jets with the largest transverse momentum (p T) within the rapidity range| y|< 2.8 are well separated (ΔR min 4j> 0.65), all have p T> 64 GeV, and include at least one jet with p T> 100 GeV. The dataset corresponds to an integrated luminosity of 20.3 fb− 1. The cross sections, corrected for detector effects, are compared to leading-order and next-to-leading-order calculations as a function of the jet momenta, invariant masses, minimum and maximum opening angles and other kinematic variables.
