无轻希格斯玻色子玻色子的MSSM扩张的自然界

Naturalness bounds in extensions of the MSSM without a light Higgs boson

Paolo Lodone

摘要:

采用自下而上的观点,我们做了一个比较研究的最简单的扩展MSSM与额外的树级贡献的最轻的希格斯玻色子质量。我们展示了在多大程度上一个相对较重的希格斯玻色子,高达200-350 GeV,可以兼容的数据和自然。付出的代价是理论在相对较低的尺度上经历了某种政权的变化。这些模型的边界来自于电弱精度测试和自然性,这通常要求软项生成的尺度相对较低。

英文摘要:

Adopting a bottom-up point of view, we make a comparative study of the simplest extensions of the MSSM with extra tree level contributions to the lightest Higgs boson mass. We show to what extent a relatively heavy Higgs boson, up to 200-350 GeV, can be compatible with data and naturalness. The price to pay is that the theory undergoes some change of regime at a relatively low scale. Bounds on these models come from electroweak precision tests and naturalness, which often requires the scale at which the soft terms are generated to be relatively low.
