利用大型强子对撞机的ATLAS探测器收集的碰撞数据，搜索通过窄共振衰减为质量范围为65-600 GeV的两个光子的标量粒子。最近发现的希格斯玻色子被当作背景。没有观察到额外信号的重要证据。结果显示为95%置信水平的极限上的生产截面的一个标量玻色子乘以分支比成两个光子，在一个基准体积，其中重建效率是大约独立于事件拓扑。设定的上限比以前的搜索范围大得多。
A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed usingofcollision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches.
