在LHC上具有Peccei-Quinn对称性和轻赝标希格斯玻色子的最小超对称标准模型的单重超场扩展

Singlet superfield extension of the minimal supersymmetric standard model with Peccei-Quinn symmetry and a light pseudoscalar Higgs boson at the LHC

Jihn E. Kim, Hans Peter Nilles, Min-Seok Seo

摘要:

受μ-问题和强CP-问题的轴子解的启发,我们将MSSM扩展为多一个手征单重场$X_e$。潜在的PQ对称性只允许超势中多一项$X_e H_u H_d$。希格斯系统的光谱包括一个轻赝标量$a_X$(除了标准的CP偶希格斯玻色子玻色子),主要衰变为两个光子:$a_X \to γγ$。这两种希格斯玻色子可能都在目前大型强子对撞机实验所能达到的范围内。

英文摘要:

Motivated by the mu-problem and the axion solution to the strong CP-problem, we extend the MSSM with one more chiral singlet field $X_e$. The underlying PQ-symmetry allows only one more term $X_e H_u H_d$ in the superpotential. The spectrum of the Higgs system includes a light pseudoscalar $a_X$ (in addition to the standard CP-even Higgs boson), predominantly decaying to two photons: $a_X \to γγ$. Both Higgs bosons might be in the range accessible to current LHC experiments.
