A Fortran program for the calculation of the decay widths and branching
ratios of the Higgs bosons in the complex 2HDM.
Description:
The Fortran program C2HDM_HDECAY calculates the decays of
the Higgs bosons in the complex 2HDM. It includes
the most important
higher-order QCD effects and consistently neglects all EW corrections.
Files:
C2HDM_HDECAY consists of the main program file
hdecay.f. Further linked routines are
dmb.f, elw.f, feynhiggs.f, haber.f, hgaga.f,
hgg.f, hsqsq.f, susylha.f.
The input file is named
hdecay.in. It is the original hdecay.in
input file supplemented by additional input values for the
choice of the C2HDM type and the setting of the various
mass values and parameters. The meaning of these
input values is explained in the header of the file hdecay.f. The output files which are
generated are br.Hia_C2HDM, brHib_C2DM, brHic_2DM, brH3d_C2HDM
(for the neutral Higgs bosons Hi, i=1,2,3), br.cj_C2HDM (j=1,2,3 for the charged Higgs boson).
Note that the Standard Model decay widths and branching ratios are
obtained by setting COUPVAR=0, I2HDM=0 and IC2HDM=0 in the input file.
Be aware that, unless OMIT ELW is set to 1,
they do not correspond to the C2HDM results for the SM-like Higgs boson.
The reason is that
the EW corrections are consistently turned off in the C2HDM case.
