HiggsBounds-5

HiggsBounds takes a selection of Higgs sector predictions for any particular model as input and then uses the experimental topological cross section limits from Higgs searches at LEP, the Tevatron and the LHC to determine if this parameter point has been excluded at 95% C.L..

Download the newest release or take a look at the documentation.

The HiggsBounds-5 manual is available here.

Experimental Results

HiggsBounds incorporates a large number of experimental results. The list of implemented analyses can be accessed locally through the AllAnalyses executable (see below) including InspireHEP cite keys and arXiv or experimental report numbers for easy citing. An up-to date version of that list is also available here (as HBAnalyses.txt) together with a HBAnalyses.bib file and an example tex file citing all HiggsBounds analyses.

Compilation

HiggsBounds requires a Fortran compiler supporting at least Fortran 95 (like gfortran) and cmake.

The code is compiled by

mkdir build && cd build
cmake ..
make

If your distribution does not provide a recent version of CMake (e.g. Scientific Linux or CentOS) simply grab the binary version from here.

If you wish to use a different Fortran compiler set the FC environment variable before running cmake.

LEP chi-squared extension

In order to use the chi-squared values from LEP simply add

-DLEP_CHISQ=ON

to the cmake .. line. This automatically downloads the required data files (see e.g. example_programs/HBwithLEPlikelihood.F90 for an example using this extension).

FeynHiggs examples

Some of the example_programs illustrate the use of HiggsBounds together with FeynHiggs. To use these a compiled version of FeynHiggs is required and

-DFeynHiggs_ROOT=/path/to/feynhiggs

has to be set in the to the cmake .. line. See e.g. example_programs/HBwithFH.F90 for an example.

Tests

A test suite that checks the results of the example codes against reference values is included and can be executed through make check or (for more detailed results) ctest --output-on-failure. Running the tests requires python>3.5 with the pytest, numpy and pandas packages. The test suite takes a few minutes to complete.

Library

HiggsBounds can be used as a library of Fortran subroutines (see src/HiggsBounds_subroutines.F90 and the subroutine documentation) by linking the build/lib/libHB.a library. If your project builds using CMake you can simply use

find_package(HiggsBounds)
# ...
target_link_libraries(YourTarget PRIVATE HiggsBounds::HB)

and CMake will take care of everything else.

C Interface

HiggsBounds provides a C interface in include/HiggsBounds.h that wraps the Fortran subroutines and takes care of type conversions. When using the C interface, make sure to link any libraries required by the Fortran C interface of your compiler setup (e.g. -lgfortran -lm -lquadmath -lm for gcc-gfortran). If you use CMake this will be handled automatically.

Executables

Compilation generates a binary which can be invoked from the command line as

./HiggsBounds <options>

In addition an AllAnalysis executable which prints all implemented experimental results, and all example_programs whose dependencies are met are compiled.
