Home of FeynHiggs
FeynHiggs is a Fortran code for the
(diagrammatic) calculation of the masses, mixings and much more of the
Higgs bosons in the MSSM with real/complex parameters at the highest
level of accuracy.

Newest version: FeynHiggs2.14.4
Upgrade information:
To upgrade from FeynHiggs2.13.0 to
FeynHiggs2.14.0 or higher you have to adjust
[FHSetFlags].
To upgrade from FeynHiggs2.12.2 to
FeynHiggs2.13.0 or higher you have to adjust FHSetSMPara, and if
used also FHGetPara and/or FHConstraints (and
possibly use the new
[FHEWPO]).
To upgrade from FeynHiggs2.11.3 to
FeynHiggs2.12.0 or higher you have to adjust FHSetFlags
(See "what happened/history" below).

What happened (FeynHiggs2.14.4):
- Implemented two-loop Δb corrections from
arXiv:1001.1935
(thanks to Michael Spira for providing the full expressions).
This correction is activated by setting the flag botresum = 2. While
the two-loop corrections are always included in the calculation of
the Higgs decay widths, they enter the calculation of the Higgs masses only
for looplevel = 1. This restriction to looplevel = 1 is a
temporary feature that will be lifted once the
implementation of the corrections from
arXiv:1705.07909
is completed. Thanks go to Ivan Sobolev.
- Fixed bug in the calculation of MSbar vev leading to changes
in the SM-like Higgs mass of O(0.1) GeV.
- Fixed bug for the flag runningMT = 1 leading to changes in the SM-like
Higgs mass of O(0.1) GeV.
- Fixed bug in case of DRbar sfermion input parameters leading
to changes in the SM-like Higgs mass of O(0.5) GeV for large
Ab. Thanks go to Ivan Sobolev.
