在Tevatron上对高质量标准模型希格斯玻色子的研究

Searches for a high mass Standard Model Higgs boson at the Tevatron

S. Pagan Griso

摘要:

希格斯玻色子玻色子的研究是当今粒子物理学的主要目标之一。CDF和D 0合作获得的最新结果在这里介绍时,寻找希格斯玻色子衰变成W玻色子对,目前最敏感的通道质量大于130 GeV。所给出的结果是基于积分亮度,其范围为3.0 ~ 4.2 fb^-1。没有观察到超过预期背景的显著过量,并且为标准模型(SM)希格斯玻色子设定了95%CL限值,用于100 GeV至200 GeV范围内的不同质量假设。结合CDF和D 0的结果,首次排除了SM希格斯玻色子在160 < mH < 170 GeV的质量范围。

英文摘要:

Higgs boson searches are commonly considered one of the main objectives of particle physics nowadays. The latest results obtained by the CDF and D0 collaborations are presented here when searching for Higgs boson decaying into a W-boson pair, currently the most sensitive channel for masses greater than 130 GeV. The presented results are based on an integrated luminosity that ranges from 3.0 to 4.2 fb^-1. No significant excess over expected background is observed and the 95% CL limits are set for a Standard Model (SM) Higgs boson for different mass hypotheses ranging from 100 GeV to 200 GeV. The combination of CDF and D0 results is also presented, which exclude for the first time a SM Higgs boson in the 160 < mH < 170 GeV mass range.
