论文摘要
介绍了公共代码$ \ texttt {feynhiggs} $的最新预测，以预测最小的超对称标准模型中标准模型的希格斯质量。基于有效场理论的预测的改进涉及多尺度层次结构的案例，即Gluino比Sfermions重得多，或者附加的Higgs玻色子在电动线和超对称量表之间具有质量。通过重新实现和扩展两环校正的重新实现和扩展，现在包含订单的贡献$ \ big（α_t+α_b\ big）\ cdot \ big（α_t+α_b+α_s\ big）$在限制范围的电动台上的限制中，以重新实现所有实现的量。更新的版本具有显着提高的数值稳定性，因此对于具有重型超对称颗粒的方案的适用性增强了。所有更新将包含在即将发布的版本$ \ texttt {feynhiggs-2.19.0} $中。
Recent developments in the public code $\texttt{FeynHiggs}$ for the prediction of the Standard Model-like Higgs mass in the Minimal Supersymmetric Standard Model are presented. Improvements in the prediction based on an effective-field theory concern the cases of multi-scale hierarchies where the gluino is much heavier than the sfermions or where the additional Higgs bosons have masses between the electroweak and supersymmetry scales. The fixed-order part is improved by a re-implementation and extension of the two-loop corrections, now containing the contributions of orders $\big(α_t+α_b\big)\cdot\big(α_t+α_b+α_s\big)$ in the limit of vanishing electroweak gauge couplings for all implemented renormalization schemes. The updated version has a significantly improved numerical stability and thus an enhanced range of applicability for scenarios with heavy supersymmetric particles. All updates will be included in the upcoming version $\texttt{FeynHiggs-2.19.0}$.
