SUSY希格斯玻色子玻色子和更远的

SUSY Higgs bosons and beyond

Marcela Carena, Eduardo Pontón, José Zurita

摘要:

我们考虑扩展的最小超对称标准模型(MSSM)的额外的自由度弱相互作用的希格斯部门。这些模型允许放松最轻的CP甚至希格斯质量从直接LEP搜索的下限和MSSM的理论上限之间的张力。我们用有效场论方法研究了超MSSM效应,假设MSSM在重物理尺度M下是有效的。我们计算了希格斯扇区的质量、耦合和分支分数,包括直到1/M^2阶的所有相关修正。我们发现,对撞机现象可以大大不同的SM和MSSM。

英文摘要:

We consider extensions of the Minimal Supersymmetric Standard Model (MSSM) where the extra degrees of freedom interact weakly with the Higgs sector. These models allow to relax the tension between the lower bound on the lightest CP even Higgs mass from direct LEP searches and the theoretical upper bound of the MSSM. We study the beyond MSSM (BMSSM) effects via an effective field-theory approach, assuming that the MSSM is valid up to a heavy physics scale M. We compute the masses, couplings and branching fractions of the Higgs sector, including all the relevant corrections up to order 1/M^2. We find that the collider phenomenology can be greatly different with respect to both the SM and the MSSM.
