None Higgs classification in Geant4 

Forum: Particles
Date: 07 Nov, 2014
From: Leonardo Di Matteo <Leonardo Di Matteo>

Dear Geant4 experts,

	we would like to simulate LHC events recorded with the CMS detector 
where the Higgs Boson decays into invisible objects.

From past studies, it seems that one way this is achievable is to set the 
Higgs as stable object (status 1 in Pythia6), and then pass this to Geant4.

I would like to understand how exactly Geant4 treats this stable Higgs.

It seems to me that we would need this particle to be treated as "geantino".
Now, is this what happens? Is Geant4 seeing a stable particle with PDGID = 25 
(the higgs one) and thus classifies it as invisible? Or is this particle 
simply discarded by Geant4?

Thanks for your help,
Leonardo
