Is it possible to generate process p p > h > z a

Asked by Helen Hayward

Hi,
I would like to generate some p p > h > z a events (and p p > h j j , h > z a ).
If I choose the "heft" model I can successfully generate p p > h > z z and p p > h > a a , but the process h > z a does not seem possible.

Command "generate p p > h > z a" interrupted with error:
InvalidCmd : No amplitudes generated from process Process: g/u/c/d/s/u~/c~/d~/s~ g/u/c/d/s/u~/c~/d~/s~ > h> z a HIG=1 HIW=1 WEIGHTED=4. Please enter a valid process

Is this process included in any of the available madgraph models?

Thanks for your question.
Olivier Mattelaer is away for a week and he aksed me to inform
the mg5 users that he will answer mg5 questions on next Sunday.

Thanks for your patience,

Hi Helen,

You need a special model for this.
You should have exactly all the information that you need on the following webpage:

Cheers,

Olivier

Hi Olivier,

I'm also interested in the process h > z a, but the link you posted above doesn't seem to exist. Is there somewhere else I can find out about the model needed to calculate this process?

Hi Ben,

Thanks for pointing this to me. Antoine left physics but in principle the web page was still suppose to be up.
(In fact I have no idea why this is not working). I've move the file to my personal area and now it is working.:

Cheers,

Olivier,

The new location works, and I was able to download, import, and run the h>Zgamma model successfully. Thanks!

Ben
