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: FeynHiggs2.13.0-beta
Upgrade information:
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]).
(see "what happened/history" below).
To upgrade from FeynHiggs2.11.3 to
FeynHiggs2.12.0 or higher you have to adjust FHSetFlags
(see "what happened/history" below).

Last update: February 11, 2017
What happened (FeynHiggs2.13.0-beta):
- looplevel = 0, 1 can now consistently be called with loglevel =
0, 2, 3 (we are working on 1).
For high SUSY mass scales, where numerical instabilities can occur
in the Feynman-diagrammatic calculation, those corrections can be
switched off at the users's will (looplevel = 0 corresponds to a pure EFT
calculation). Still experimental!
- For loglevel > 1 the one-loop and
O(αtαs) threshold corrections are now
more complete (extension to the case of non-degenerate soft
SUSY-breaking parameters, inclusion of missing term in the matching
conditions of the effective Higgs-Higgsino-EWino couplings). The numerical
effect on Mh is mostly small, O(100 MeV).
Thanks to Pietro Slavich for providing the general expression for
the O(αtαs) threshold correction.
- Interpolation of the EFT calculation in the case of complex parameters
included.
- The flag tlCplxApprox now has only the (previously) allowed
values 0, 1, 2, 3. The choice of the parameters for the complex
interpolation, previously done by setting tlCplxApprox = 3, 4, 5, 6
is now done by calling
FHSelectIpol or by
setting the environment variable FHSELECTIPOL.
- Higgs production cross sections for WBF, ZH, WH, ttH at
13 TeV included and for 14 TeV updated.
SM cross sections are taken from the
LHCHXSWG.
(ttH@14 TeV still missing.)
- The electroweak precision observables have been improved and
reorganized. Thanks go to Lisa Zeune!
- The EWPO are now evaluated calling the new routine
FHEWPO.
- Δr is now evaluated in the SM and MSSM. In the SM it is
given via a Fit formula from
hep-ph/0608099.
In the MSSM it is based on
arXiv:1311.1663 [hep-ph]
(by L. Zeune et al.)
It contains a full one-loop calculation in the cMSSM and two-loop
corrections to Δρ interpolated for the complex
parameters.
- The Δρ output now contains the one loop contribution
from the third generation of (s)quarks,
the gluon and gluino two-loop corrections (and the one
from the sbottom mass shift).
- Bug in the call of the flavor observables removed.
