Implementation of the $\mathcal{O}\left({\alpha }_t^2\right)$ MSSM Higgs-mass corrections in $\mathtt{FeynHiggs}$

Abstract

We describe the implementation of the two-loop Higgs-mass corrections of $\mathcal{O}\left({\alpha }_t^2\right)$ in the complex MSSM in $\mathtt{FeynHiggs}$. The program for the calculation is included in $\mathtt{FeynHiggs}$ and documented here in some detail such that it can be re-used as a template for similar calculations.
