我们提出了一个扩展的Mathematica packageSARAH，它允许希格斯质量计算在两个循环的水平在广泛的超对称（SUSY）模型超出MSSM。这些计算是基于有效势的方法，并包括所有的两个回路的修正是独立的电弱规范耦合。对于数值计算Fortran代码forSphenois生成的SARAH。这允许在更复杂的超对称模型中预测希格斯质量，其精度与大多数最先进的光谱发生器为MSSM提供的精度相同。
We present an extension to the Mathematica packageSARAHwhich allows for Higgs mass calculations at the two-loop level in a wide range of supersymmetric (SUSY) models beyond the MSSM. These calculations are based on the effective potential approach and include all two-loop corrections which are independent of electroweak gauge couplings. For the numerical evaluation Fortran code forSPhenois generated bySARAH. This allows the prediction of the Higgs mass in more complicated SUSY models with the same precision that most state-of-the-art spectrum generators provide for the MSSM.
