Fully Automated Calculations in the complex MSSM

T. Hahn, S. Heinemeyer, F. von der Pahlen, H. Rzehak, C. Schappacher

摘要:

我们回顾了最近的进展,自动高阶计算MSSM与复杂的参数(cMSSM)。cMSSM的所有相关部门的一致重整化和纳入FeynArts/FormCalc框架最近已经完成。一些例子计算应用这个框架进行了简要讨论。这些包括对cMSSM希格斯玻色子玻色子质量的双环修正,以及电弱超对称粒子衰变为一个希格斯玻色子玻色子和另一个超对称粒子的部分衰变宽度。

英文摘要:

We review recent progress towards automated higher-order calculations in the MSSM with complex parameters (cMSSM). The consistent renormalization of all relevant sectors of the cMSSM and the inclusion into the FeynArts/FormCalc framework has recently been completed. Some example calculations applying this framework are briefly discussed. These include two-loop corrections to cMSSM Higgs boson masses as well as partial decay widths of electroweak supersymmetric particles decaying into a Higgs boson and another supersymmetric particle.
