寻找新的重粒子表现为共振在两个射流的最终状态。这些数据是由LHC在7 TeV质子-质子碰撞中产生的，对应于ATLAS探测器收集的315 nb（-1）的积分光度。未观察到共振。上限被设置在作为q* 质量的函数的激发夸克（q*）产生的截面和信号接受的乘积上。这些排除在95% C。L. q* 质量间隔0：30< m（q）*< 1：26 TeV，扩展了先前实验的范围。
A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315 nb(-1) collected by the ATLAS detector. No resonances were observed. Upper limits were set on the product of cross section and signal acceptance for excited-quark (q*) production as a function of q* mass. These exclude at the 95% C. L. the q* mass interval 0: 30< m(q)*< 1:26 TeV, extending the reach of previous experiments.
