Precision calculations in the MSSM Higgs-boson sector with FeynHiggs\n 2.14

We present an overview of the status and recent developments of FeynHiggs\n(current version: 2.14.3) since version 2.12.2. The main purpose of FeynHiggs\nis the calculation of the Higgs-boson masses and other physical observables in\nthe MSSM. For a precise prediction of the Higgs-boson masses for low and high\nSUSY scales, state-of-the-art fixed-order and effective-field-theory\ncalculations are combined. We first discuss improvements of the fixed-order\ncalculation, namely an optional $\\overline{\\text{DR}}$ renormalization of the\nstop sector and a renormalization of the Higgs sector ensuring the chosen input\nmass to be equivalent with the corresponding physical mass. Second, we describe\nimprovements of the EFT calculation, i.e. an implementation of non-degenerate\nthreshold corrections as well as an interpolation for complex parameters.\nLastly, we highlight some improvements of the code structure easing future\nextensions of FeynHiggs to models beyond the MSSM.\n
