助推希格斯粒子在NMSSM中衰变为γ和Z

Boosting Higgs decays into gamma and a Z in the NMSSM

G. Belanger, V. Bizouard, G. Chalons

摘要:

本文在次极小超对称标准模型(NMSSM)框架下,在单圈水平上计算了Higgs粒子衰变为光子和$Z^0$玻色子的过程.该衰减宽度的数值评估是在SloopS代码的框架内进行的,该代码最初是为最小超对称标准模型(MSSM)开发的,但最近扩展到处理NMSSM。由于SloopS的高度自动化,NMSSM各个部门的所有贡献都得到了一致的考虑,特别是非对角电荷和sfermion的贡献。然后,我们探索了NMSSM参数空间,使用HiggsBounds和HiggsSignals,研究这些信号可以增强到什么程度。

英文摘要:

In this work we present the computation of the Higgs decay into a photon and a $Z^0$ boson at one-loop level in the framework of the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The numerical evaluation of this decay width was performed within the framework of the SloopS code, orginally developped for the Minimal Supersymmetric Standard Model (MSSM) but which was recently extended to deal with the NMSSM. Thanks to the high level of automation of SloopS all contributions from the various sector of the NMSSM are consistently taken into account, in particular the non-diagonal chargino and sfermion contributions. We then explored the NMSSM parameter space, using HiggsBounds and HiggsSignals, to investigate to which extent these signal can be enhanced.
