本文报道了在具有大的横向动量丢失和希格斯玻色子衰变为两个光子的事件中寻找新现象的结果。质子-质子碰撞的数据在质心能量为8 TeV和对应的积分光度的已收集与ATLAS探测器在大型强子对撞机。观测数据很好地描述了预期的标准模型背景。的横截面上的事件与大失踪的横向动量和希格斯玻色子候选人的上限也被放置。排除限制的物理模型超出了标准模型具有暗物质的候选人。
Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and corresponding to an integrated luminosity ofhave been collected with the ATLAS detector at the LHC. The observed data are well described by the expected standard model backgrounds. Upper limits on the cross section of events with large missing transverse momentum and a Higgs boson candidate are also placed. Exclusion limits are presented for models of physics beyond the standard model featuring dark-matter candidates.
