标准电弱模型中希格斯玻色子的质量

The Mass of the Higgs Boson in the Standard Electroweak Model

Jens Erler

摘要:

更新的标准模型(SM)内的所有相关的电弱精度和希格斯玻色子搜索数据的全球分析,特别强调希格斯玻色子质量,M_H的影响。包括,特别是,最新的结果上的顶夸克和W玻色子的质量,更新和显着转移的约束强耦合常数,α_s,从τ衰变和其他低能量的测量,如从原子宇称违反和中微子深非弹性散射。在Tevatron的希格斯生产和衰变搜索的最新结果与LEP 2的旧约束结合在一起。我们发现M_H的三峰几率分布具有一个相当窄的90%CL窗口,115 GeV <M_H <148 GeV.

英文摘要:

An updated global analysis within the Standard Model (SM) of all relevant electroweak precision and Higgs boson search data is presented with special emphasis on the implications for the Higgs boson mass, M_H. Included are, in particular, the most recent results on the top quark and W boson masses, updated and significantly shifted constraints on the strong coupling constant, alpha_s, from tau decays and other low energy measurements such as from atomic parity violation and neutrino deep inelastic scattering. The latest results from searches for Higgs production and decay at the Tevatron are incorporated together with the older constraints from LEP 2. I find a trimodal probability distribution for M_H with a fairly narrow preferred 90% CL window, 115 GeV < M_H < 148 GeV.
