这封信描述了一个模型无关的搜索生产新的共振态的事件中的质子-质子碰撞。我们比较themass分布的背景模型来自数据，并发现与背景的假设一致。由于缺乏信号的证据，我们对通用高斯形信号和基准激发夸克（）模型设置了95%的可信度限制，分别排除了截面时间分支分数时间接受时间效率接近5 fb的2 TeV高斯共振和低于2.46 TeV的质量。
This Letter describes a model-independent search for the production of new resonant states inevents inof proton-proton collisions at. We compare themass distribution to a background model derived from data and find consistency with the background-only hypothesis. Given the lack of evidence for a signal, we set 95% credibility level limits on generic Gaussian-shaped signals and on a benchmark excited-quark () model, excluding 2 TeV Gaussian resonances with cross section times branching fraction times acceptance times efficiency near 5 fb and excludingmasses below 2.46 TeV, respectively.
