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

Understand

We present an overview of the status and recent developments of FeynHiggs (current version: 2.14.3) since version 2.12.2.

• The main purpose of FeynHiggs is the calculation of the Higgs-boson masses and other physical observables in the MSSM.
• For a precise prediction of the Higgs-boson masses for low and high SUSY scales, state-of-the-art fixed-order and effective-field-theory calculations are combined.
• We first discuss improvements of the fixed-order calculation, namely an optional $\overline{\text{DR}}$ renormalization of the stop sector and a renormalization of the Higgs sector ensuring the chosen input mass to be equivalent with the corresponding physical mass.
