MSSM与FeynHiggs复合体中的Higgs质量及更多

Higgs Masses and More in the Complex MSSM with FeynHiggs

T. Hahn, S. Heinemeyer, W. Hollik, H. Rzehak, G. Weiglein

摘要:

我们提出了最新版本2.6的FeynHiggs,用于计算MSSM希格斯玻色子质量和相关观测值,如混合角,分支比和耦合,包括国家的最先进的高阶贡献的程序。其中最重要的新特点是引入了全复O(α t α s)双圈修正,这使得FeynHiggs在费曼图解法中给出了迄今为止最精确的复MSSM中Higgs质量的计算.

英文摘要:

We present the latest version 2.6 of FeynHiggs, a program for computing MSSM Higgs-boson masses and related observables, such as mixing angles, branching ratios, and couplings, including state-of-the-art higher-order contributions. The most important new feature is the inclusion of the fully complex O(α_tα_s) two-loop corrections, which enables FeynHiggs to give the most precise Higgs-mass evaluation in the complex MSSM in the Feynman-diagrammatic approach to date.
