用超对称质量项和轻单重态解族问题

Solving the Hierarchy Problem with a Light Singlet and Supersymmetric Mass Terms

Antonio Delgado, Christopher Kolda, Alejandro de la Puente

摘要:

研究了次极小超对称模型(NMSSM)的一个推广,其中引入了一个显式的μ项和一个小的超对称质量项.我们研究了通过与一个轻的、大部分为单重态的CP偶标量混合,在树的水平上提高标准模型类希格斯质量的可能性。我们能够产生质量高达145 GeV的希格斯玻色子,顶部的平方低于1.1 TeV,而不需要微调参数的标量势。这个模型产生轻单态样标量和pseudoscalars通过所有的对撞机的限制。

英文摘要:

A generalization of the Next-to-Minimal Supersymmetric Model (NMSSM) is studied in which an explicit μ-term as well as a small supersymmetric mass term for the singlet superfield are incorporated. We study the possibility of raising the Standard Model-like Higgs mass at tree level through its mixing with a light, mostly-singlet, CP-even scalar. We are able to generate Higgs boson masses up to 145 GeV with top squarks below 1.1 TeV and without the need to fine tune parameters in the scalar potential. This model yields light singlet-like scalars and pseudoscalars passing all collider constraints.
