标题： Theoretical Aspects of Higgs Physics

摘要： 我们回顾了标准模型及其扩展模型中的希格斯物理现状。 首先，我们简要总结了来自LEP1和Tevatron直接搜索的当前实验排除限，并评估了LEP2的发现潜力。 然后，我们报告了基于最新电弱精确数据全局拟合得出的质量界限，并整理了各种导致限制——甚至确定——希格斯玻色子质量的理论原理。 详细讨论了微扰论上的上限。 最后，我们综述了标准模型希格斯玻色子bb-bar衰变宽度高阶辐射修正计算的近期进展。 显示英文摘要

摘要： We review the present status of Higgs physics within the standard model and its extensions. First, we briefly summarize the current experimental exclusion limits from the direct searches with LEP1 and the Tevatron, and assess the discovery potential of LEP2. Then, we report the mass bounds resulting from global fits to the latest electroweak precision data, and compile various theoretical principles which lead to restrictions - or even determinations - of the Higgs-boson masses. Perturbative upper bounds are discussed in some detail. Finally, we survey the recent progress in the computation of higher-order radiative corrections to the bb-bar decay width of the standard-model Higgs boson.
