在大型强子对撞机上用ATLAS探测器搜索标准模型希格斯玻色子

Standard Model Higgs boson searches with the ATLAS detector at the Large Hadron Collider

Aleandro Nisati

摘要:

研究电弱对称性破缺的机制是大型强子对撞机科学计划的重要任务之一。介绍并讨论了利用ATLAS探测器记录的1到2 fb^-1的质子质子碰撞数据(s=7 TeV)搜索标准模型希格斯玻色子的实验结果。相对于标准模型过程的预期,没有发现显著的过量事件,并且对于质量区域144-232、256-282和296-466 GeV,在95%置信水平下排除了希格斯玻色子的产生。

英文摘要:

The investigation of the mechanism responsible for electroweak symmetry breaking is one of the most important tasks of the scientific program of the Large Hadron Collider. The experimental results on the search of the Standard Model Higgs boson with 1 to 2 fb^-1 of proton proton collision data at sqrt s=7 TeV recorded by the ATLAS detector are presented and discussed. No significant excess of events is found with respect to the expectations from Standard Model processes, and the production of a Higgs boson is excluded at 95% Confidence Level for the mass regions 144-232, 256-282 and 296-466 GeV.
