在ATLAS中寻找双光子末态的标准模型希格斯玻色子

Search for Standard Model Higgs boson in the two-photon final state in ATLAS

Olivier Davignon

摘要:

我们报告的搜索标准模型希格斯玻色子衰变成两个光子的基础上质子-质子碰撞数据的质量中心的能量为7 TeV的ATLAS实验在LHC。该数据集的积分亮度约为1.08 fb-1。在双光子质量范围110 - 150 GeV内,预期的截面排除在95%置信水平下在标准模型截面的2.0和5.8倍之间变化。与仅背景期望的最大偏差与统计波动一致。

英文摘要:

We report on the search for the Standard Model Higgs boson decaying into two photons based on proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The dataset has an integrated luminosity of about 1.08 fb-1. The expected cross section exclusion at 95% confidence level varies between 2.0 and 5.8 times the Standard Model cross section over the diphoton mass range 110 - 150 GeV. The maximum deviations from the background-only expectation are consistent with statistical fluctuations.
