Model files

• ​HEIDI.fr: FeynRules model file, requires ​Heidi.m and ​Hdecay.m to function.
• ​Heidi.m: Standalone spectrum generator, requires ​Hdecay.m to function.
• ​Hdecay.m: Parameterized ​HDECAY output.
• ​HEIDI_bundle.fr: Standalone bundle.

Instructions

The model can be used either via the standalone bundle HEIDI_bundle.fr or via the 'pure' model file HEIDI.fr. Please note that the latter does not include Heidi.m and Hdecay.m which therefore have to be downloaded (see above) and put into the mathematica search path separately. The model is intended to be used on top of SM.fr, e.g. via LoadModel["SM/SM.fr", "HEIDI.fr"]. Prior to loading, several flags have to be set which determine the scalar spectrum, please take a look at ​arXiv:1010.3251 for further details.

Notes

At the moment, the model only supports unitarity gauge. In addition, the effective gluon fusion couplings are not compatible with the MadGraph interface at the moment. Both restrictions will be removed in a future revision.
