LHC希格斯玻色子搜索

LHC Higgs Boson searches

William Murray

摘要:

本文介绍了利用大型强子对撞机(LHC)1 f b-1的数据,通过ATLAS和CMS协作对希格斯玻色子玻色子的研究,重点讨论了标准模型希格斯玻色子玻色子。这两个实验都具有在95% CL下排除标准模型希格斯玻色子的灵敏度,该标准模型中的大部分希格斯玻色子质量区域在约130 GeV和400 GeV之间。观测到的数据允许排除质量为155 GeV至190 GeV和295 GeV至450 GeV(ATLAS)以及149 GeV至206 GeV和300 GeV至440 GeV(CMS)的希格斯玻色子。下限并不像预期的那样受限制,这是因为在两个2-3σ阶的实验中都有过量,这可能与低质量的希格斯玻色子或统计涨落有关。

英文摘要:

A summary of the Higgs boson searches by the ATLAS and CMS collabrations using 1 f b-1 of LHC data is presented, concentrating on the Standard Model Higgs boson. Both experiments have the sensitivity to exclude at 95% CL a Standard Model Higgs boson in most of the Higgs boson mass region between about 130 GeV and 400 GeV. The observed data allow the exclusion of a Higgs Boson of mass 155 GeV to 190 GeV and 295 GeV to 450 GeV (ATLAS) and 149 GeV to 206 GeV and 300 GeV to 440 GeV (CMS). The lower limits are not as constraining as might be expected due to an excess in both experiments of order 2-3σ which could be related to a low mass Higgs boson or to a statistical fluctuation.
