Abstract FeynHiggs is a Fortran code for the calculation of the masses of the neutral CP-even Higgs bosons in the MSSM up to two-loop order. It is based on the complete diagrammatic on-shell result at the one-loop level, the leading diagrammatic two-loop QCD contributions and further improvements taking into account leading electroweak two-loop and leading higher-order QCD corrections. The Higgs-boson masses are calculated as functions of the MSSM parameters for general mixing... Title of program: FeynHiggs Catalogue Id: ADKT_v1_0 Nature of problem The masses of the neutral CP-even Higgs bosons in the MSSM can be calculated in terms of the other model parameters. Large corrections to the masses at the one-loop level require a two-loop calculation. Versions of this program held in the CPC repository in Mendeley Data ADKT_v1_0; FeynHiggs; 10.1016/S0010-4655(99)00364-1 ADKT_v2_0; FeynHiggs v2.6.5; 10.1016/j.cpc.2009.02.014 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)

摘要 FeynHiggs是一款Fortran编程语言编写的代码,旨在计算MSSM(最小超对称标准模型)中中性CP偶数Higgs玻色子的质量,计算精度可达二重循环阶。该代码基于一重循环阶完全图示在壳结果,主导图示二重循环QCD贡献,以及进一步考虑主导电弱二重循环和主导高阶QCD校正的改进。Higgs玻色子的质量被计算为MSSM参数的函数,适用于一般混合情形... 程序名称:FeynHiggs 目录编号:ADKT_v1_0 问题性质 在MSSM中,中性CP偶数Higgs玻色子的质量可以通过其他模型参数来计算。一重循环阶质量的大校正需要二重循环计算。 本程序版本存放在Mendeley Data中的CPC程序库 ADKT_v1_0;FeynHiggs;10.1016/S0010-4655(99)00364-1 ADKT_v2_0;FeynHiggs v2.6.5;10.1016/j.cpc.2009.02.014 本程序已从贝尔法斯特女王大学(1969-2018)所持有的CPC程序库导入。
