给出了寻找大质量粒子到完全强子最终态的衰变的结果。这项研究使用了ATLAS探测器在大型强子对撞机上√s=8 TeV质子-质子碰撞中收集到的20.3 fb−1的数据。利用基于高喷流多重度而不需要缺少横向动量的特征来搜索违反r宇称的超对称胶子对产生并随后衰变为夸克。分析使用对射流数量的需求，结合对b标记射流数量的单独需求，以及由事件中大半径射流质量值的标量和形成的拓扑观测值来执行。结果在直接胶子衰变到各种夸克口味的所有可能分支比的背景下解释。使用喷流计数和数据驱动的总喷流-质谱模板估计的预期标准模式背景没有明显偏差。对于质量为mg ~ <1 TeV的胶子和质量为mχ ~ 01=500 GeV的胶子，胶子对通过中间中性子衰变成10个或更多的夸克是不存在的。在mg ~ <917 GeV的轻风味终态中，排除了直接胶子衰变到6夸克的可能性，并给出了各种风味假设的结果。
Results of a search for decays of massive particles to fully hadronic final states are presented. This search uses 20.3 fb−1 of data collected by the ATLAS detector in √s=8 TeV proton-proton collisions at the LHC. Signatures based on high jet multiplicities without requirements on the missing transverse momentum are used to search for R-parity-violating supersymmetric gluino pair production with subsequent decays to quarks. The analysis is performed using a requirement on the number of jets, in combination with separate requirements on the number of b-tagged jets, as well as a topological observable formed from the scalar sum of the mass values of large-radius jets in the event. Results are interpreted in the context of all possible branching ratios of direct gluino decays to various quark flavors. No significant deviation is observed from the expected Standard Model backgrounds estimated using jet counting as well as data-driven templates of the total-jet-mass spectra. Gluino pair decays to ten or more quarks via intermediate neutralinos are excluded for a gluino with mass mg˜<1 TeV for a neutralino mass mχ˜01=500 GeV. Direct gluino decays to six quarks are excluded for mg˜<917 GeV for light-flavor final states, and results for various flavor hypotheses are presented.
