Generating higgs decay to vector meson

Asked by Yehia Abdelaziz

Hey there, I am new to all of this so bear with me. The thing is I want to generate a process where a higgs boson decays into a vector meson and a photon but I can't do this in madgraph there isn't any meson options in madgraph, I can't find a meson particle how should I do it?

Thanks

Hi,

You need first to find a UFO model that correspond to your model/physics that you want to consider.
then you can import such model within MG5aMc via the command "import model".

If you do not find the model that you are looking for online. Then you will need to implement it yourself in FeynRules (or other similar code).

Cheers,

Olivier

The thing is the interaction is supposed to be a standard model interaction.

The standard model does not have any vector meson.
So the same answer holds, you need to have a dedicated UFO model with the information about that interaction if you want to have that part within MG5aMC.

Cheers,

Olivier
