HEFT model implementation

Asked by audiya fatihah on 2021-01-27

hi, im trying to implement the HEFT model
Higgs_Effective_Couplings_UFO.tgz from http://feynrules.irmp.ucl.ac.be/wiki/HiggsEffectiveTheory

i did a simple

>import model HEFT
> generate p p > h > l+ l- l+ l-
> Detector = delphes
> set nevents 500000
>set mmll 4.0

but im getting this error

Hi,

you can do
>> set group_subprocesses False

>> generate p p > h > l+ l- l+ l-
>> Detector = delphes
>> set nevents 500000
>> set mmll 4.0

The first line de-activate (a lot) of optimization including the one that prevent the use of the mmll cut for your process

Cheers,

Olivier

PS: Another option, is to use massive lepton
