论文摘要
我们提出了基于FlexibleEfthiggs Hybrid方法的MSSM中光CP-even Higgs玻色子质量的改进计算。该计算将大量对数与所有订单恢复，并按固定顺序包含功率抑制的项。它使用最新的2和3循环匹配的四分之一的耦合和重新归一化组的运行量最高为4循环，从而导致大量对数校正的重新介绍，最高为n $^3 $ ll Level。从概念上讲，新颖的成分是匹配条件的扩展，而不是高尺度的MSSM参数而不是SM参数。通过这种方式，在定格参数中引导术语有效地重新定位，从而改善了扰动扩展的数值收敛性。此外，避免循环校正的双重计数比其他方法更透明，并且更独立于高规模模型。我们提出了数值结果，并详细讨论了标准基准方案的理论不确定性。
We present an improved calculation of the light CP-even Higgs boson pole mass in the MSSM based on the FlexibleEFTHiggs hybrid method. The calculation resums large logarithms to all orders and includes power-suppressed terms at fixed order. It uses state-of-the-art 2- and 3-loop matching of the quartic Higgs coupling and renormalization group running up to 4-loop, resulting in a resummation of large logarithmic corrections up to N$^3$LL level. A conceptually novel ingredient is the expansion of the matching conditions in terms of high-scale MSSM parameters instead of SM parameters. In this way leading terms in the stop-mixing parameter are effectively resummed, leading to an improved numerical convergence of the perturbative expansion. Furthermore, the avoidance of double counting of loop corrections is more transparent than in other approaches and more independent of the high-scale model. We present numerical results and a detailed discussion of theoretical uncertainties for standard benchmark scenarios.
