2HDMC - Two-Higgs-Doublet Model Caclulators -

2HDMC is a general-purpose calculator for the two-Higgs doublet model. It allows parametrization of the Higgs potential in many different ways, convenient specification of generic Yukawa sectors, the evaluation of decay widths (including higher-order QCD corrections), theoretical constraints and much more.

Version used: 2HDMC1.8.0 and Sushi1.7.0.

Install in a CMSSW release:

    # setup your env : for cp3 ingrid-ui1 cluster 
    module load gcc/gcc-7.3.0-sl7_amd64 lhapdf/6.1.6-sl7_gcc73
    
    # Install a CMSSW release .eg. CMSSW_10_2_22
    cmsrel CMSSW_10_2_22
    cd CMSSW_10_2_22/src
    cmsenv
    git cms-init

    # Get and execute the install script
    wget https://raw.githubusercontent.com/kjaffel/Calculators42HDM/master/sushi_2hdmc_cmssw.sh 
    source sushi_2hdmc_cmssw.sh

Install With Conda (from @pdavid):

    # setup your env
    conda create -n SusHi170 gsl gfortran_linux-64 gxx_linux-64 gcc_linux-64
    conda activate SusHi170

    wget https://github.com/kjaffel/Calculators42HDM/master/sushi_2hdmc_conda.sh
    source sushi_2hdmc_conda.sh

Run the test:

python example/test.py

Trouble-Shooting:

lib/libsushi2HDMC.a(runthdmc.o): In function `runthdmc_':
runthdmc.f:(.text+0x13d): undefined reference to `thdmc_set_param_'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:197: bin/sushi.2HDMC] Error 1

In 2HDMC-1.8.0/Makefile replace these lines:

  -CFLAGS= -std=c++11 -Wall $(DEBUG) $(OPT)
  +CFLAGS= -std=c++11 -Wall -fPIE $(DEBUG) $(OPT)
  -SOURCES=THDM.cpp SM.cpp DecayTable.cpp Constraints.cpp Util.cpp
  +SOURCES=THDM.cpp SM.cpp DecayTable.cpp Constraints.cpp Util.cpp runTHDM.cpp

Keep an eye on the latest versions:

  • 2HDMC
  • SUSHI
  • LHAPDF
  • It can also be useful to download HiggsBounds/HiggsSignals (Note: 2HDMC work without HB/HS), since 2HDMC can interface the LEP, Tevatron and LHC constraints implemented in these codes. HiggsBounds/HiggsSignals are available:
  • HiggsBounds
  • HiggsSignals
