Auto decay of H and W
Dear Whizard Authors,
When I try to decay the 125 GeV Higgs to off shell decay products, e.g. H->WW* or H->ZZ* I get an error indicating that there is no phase space available.
I also see that W decays to off-diagonal CKM are not implemented.
Please excuse me if I have not understood how to do these things. But it seems that by now when I request auto decay all of this should be correctly implemented.
I am a great fan of your program and I look forward to using it in future.
Best Regards,
Chris Potter

Dear Chris,
the model SM (which is the standard model of WHIZARD) is flavor-diagonal as this is for most cases sufficient for collider physics. If you want a full CKM matrix, please set the model as
model = SM_CKM
The auto_decay option takes as default only two-body decays, while H -> ZZ* and H -> WW* are formally three-body decays,
namely H -> Z jj , H -> Zll, H -> Zvv etc. I think you should get them by setting
auto_decays_

I assume that this answered your question, marking as solved. Otherwise, please open the question again.
Hi Juergen,
Yes, apologies for the late response. This was exactly what I needed.
Thanks,
Chris
Thanks Juergen Reuter, that solved my question.
