gg2vv

Parton-level integrator and event generator for gg (→ H) → WW and gg (→ H) → ZZ processes

Source code for semileptonic WW and ZZ channels: gg2VV-3.1.2_semilept.tar.bz2 (see arXiv:1506.01694)
New 19Aug2015: fixed typos in amplitude/formcalc/Jamfile and squaredme.WWqqlv/SquaredME.f

Source code for 1-Higgs-Singlet extension of the SM (EWS model): gg2VV_EWS-1.1.tar.bz2 (see arXiv:1502.04113; with event generation)
New 01Aug2015: fixed typo in smp.cpp; 19Aug2015: fixed typo in omnicomp_.cpp

Current SM source code: gg2VV-3.1.7.tar.bz2
(LoopTools v2.8 required, tested with LoopTools-2.8_20120918.tar.gz)

Please use the names of the old versions, gg2WW or gg2ZZ, when citing the corresponding papers:
hep-ph/0611170 (LaTeX(US), LaTeX(EU), BibTeX) for gg (→ H) → WW → 2l2ν (different flavour)

Automated installation with included script build.sh (contributed by Doug Schouten)

Build instructions:
gg2VV-3.1.6/README
gg2VV-3.1.6/README.build_libraries (compiler dependent!)
gg2VV-3.1.6/README.mixed_precision (recommended)
gg2VV-3.1.6/README.shell_configuration
(ignore irrelevant message: ...lib/intel64/libimf.so: warning: feupdateenv is not implemented and will always fail)

Main gg2VV configuration files:
gg2VV-3.1.6/Jamrules
gg2VV-3.1.6/gg2VV/settings.cpp
gg2VV-3.1.6/gg2VV/selection.cpp

Sample installation of mixed precision version (recommended)
on lxplus.cern.ch using Intel compilers (ifort, icpc, icc):
/afs/cern.ch/user/n/nkauer/public/programs/gg2VV-3.1.6/
/afs/cern.ch/user/n/nkauer/public/libraries/
/afs/cern.ch/user/n/nkauer/public/tools/jam (build tool)
/afs/cern.ch/user/n/nkauer/public/.bashrc (shell config file -> environment variables, path, Intel compilers setup script)
The environment variable LONG_BIT is used in ./Jamrules and should be set to `getconf LONG_BIT`
/afs/cern.ch/user/n/nkauer/public/config/omniORB.cfg (omniORB config file)
Sample output: mixed_precision.out, m4l.pdf

Event generation (initialization files and small event samples in LHEF format):
