论文摘要
我们讨论了公共法规Feynhiggs的混合框架中光MSSM Higgs玻色子质量预测的各种改进,该框架结合了固定顺序和有效的现场理论结果。首先,我们讨论对数贡献的重新介绍,与底部的野川耦合成正比,包括两循环$Δ_B$重新召集。对于大型$ \tanβ$,与现有的固定阶计算相比,这些改进可以导致希格斯质量的大量向上移动。其次,我们通过完全考虑$ \ Mathcal {cp} $违反阶段的效果来改善实施的EFT计算。作为第三个改进,我们讨论了部分n $^3 $ ll重新召集。提出的改进将被实施到Feynhiggs中。
We discuss various improvements of the prediction for the light MSSM Higgs boson mass in the hybrid framework of the public code FeynHiggs, which combines fixed-order and effective field theory results. First, we discuss the resummation of logarithmic contributions proportional to the bottom-Yukawa coupling including two-loop $Δ_b$ resummation. For large $\tanβ$, these improvements can lead to large upward shifts of the Higgs mass compared to the existing fixed-order calculations. Second, we improve the implemented EFT calculation by fully taking into account the effect of $\mathcal{CP}$-violating phases. As a third improvement, we discuss the inclusion of partial N$^3$LL resummation. The presented improvements will be implemented into FeynHiggs.
