超对称希格斯玻色子及以后

Supersymmetric Higgs Bosons and Beyond

Marcela Carena, Kyoungchul Kong, Eduardo Ponton, Jose Zurita

摘要:

我们考虑超对称模型,包括粒子超出最小超对称标准模型(MSSM)的质量在TeV范围内,并耦合到MSSM希格斯部门显着。我们进行一个独立于模型的分析的频谱和耦合的MSSM希格斯场,有效的理论的MSSM自由度的基础上。最轻的CP偶态的树能级质量可以很容易地超过114 GeV的LEP界限,因此允许相对较轻的超伴子光谱,仅受直接搜索的限制。与MSSM相比,Higgs谱和耦合可以被显著修改,通常允许有趣的新衰变模式。我们还观察到类SM Higgs的胶子融合产生截面相对于标准模型和MSSM都有增强。

英文摘要:

We consider supersymmetric models that include particles beyond the Minimal Supersymmetric Standard Model (MSSM) with masses in the TeV range, and that couple significantly to the MSSM Higgs sector. We perform a model-independent analysis of the spectrum and couplings of the MSSM Higgs fields, based on an effective theory of the MSSM degrees of freedom. The tree-level mass of the lightest CP-even state can easily be above the LEP bound of 114 GeV, thus allowing for a relatively light spectrum of superpartners, restricted only by direct searches. The Higgs spectrum and couplings can be significantly modified compared to the MSSM ones, often allowing for interesting new decay modes. We also observe that the gluon fusion production cross section of the SM-like Higgs can be enhanced with respect to both the Standard Model and the MSSM.
