使用20.3 fb-1的质子-质子碰撞数据在100 s = 8 TeV的ATLAS探测器记录在大型强子对撞机的最终状态下进行搜索的物理学证据超出标准模型与多个高横向动量喷流。没有观察到超出标准模型预期的显著过量的事件，并且设置了多喷流最终状态的非标准模型产生的可见横截面的上限。被认为是各种各样的模型的黑洞和弦球的生产和衰变，并在95%的置信水平上的横截面倍接受的上限低至0.16 FB。对于这些模型，排除区域也作为主要模型参数的函数给出。
A search for evidence of physics beyond the Standard Model in final states with multiple high-transverse-momentum jets is performed using 20.3 fb-1of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC. No significant excess of events beyond Standard Model expectations is observed, and upper limits on the visible cross sections for non-Standard Model production of multi-jet final states are set. A wide variety of models for black hole and string ball production and decay are considered, and the upper limit on the cross section times acceptance is as low as 0.16 fb at the 95% confidence level. For these models, excluded regions are also given as function of the main model parameters.
