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: FeynHiggs2.14.2-beta
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).

Last update: May 17, 2018
What happened (FeynHiggs2.14.2-beta):
- Eigenvalue ordering during determination of pole masses changed
from "ascending" to "aligned with tree-level eigenstates
(h,H,A)". Should improve behavior in the vicinity of level
crossing. (Thanks go to Pietro Slavich, Stefan Liebler and Tim
Stefaniak for relentless testing.)
- In the EFT calculation for complex parameters
the O(αtαs) threshold corrections are
now interpolated correctly for complex M3.
- For DRbar stop/sbottom input:
In the hi → hj hk
calculation the stop vertex loops are now calculated with DRbar stop
parameters.
- For botResum = 0 the bottom Yukawa coupling is now evaluated via
mb(mt) · (1 – Δb)
(was mb(mb) before).
- Numerical stability of
O(αtαs) and
O(αt2) corrections to the Higgs-boson
self-energies in the cMSSM improved.
- The erroneous combination of MHp as input and the flag
tlCplxApprox = 0 is now explicitely forbidden.
- Bug in the one-loop H+- field renormalization
counterterm in the gaugeless limit has been fixed. This can lead to
very small changes in the Higgs-boson masses and ZHiggs.
- Message reporting fixed for Windows version of MFeynHiggs
(was broken since gfortran4.x).
- New configure option "--real10" for x86 extended precision
(between double and quad, check ./configure --help).
- configure changed: Cygwin build improved.
