Cannot find the vertices in vertices.py which have been displayed in diagrams

Asked by zxy on 2022-11-14

Dear Madgraph guys

Hi!

I want to remove unnecessary diagrams by removing vertexes in vertices.py. Now, the vertexes which need to be found are W+e+n1 Ze-e - W-e-ve~(where n1 is heavy neutrino), but I can't remove them in vertices.py, because the vertexes are not found in the vertices. py file. What is the reason? Or how can I remove unwanted diagrams?

Attach my vertices.py

Hi,

I do find those two that correspond to your first vertex:

For the second :
V_189 = Vertex(name = 'V_189',
               particles = [ P.e__plus__, P.e__minus__, P.Z ],
               color = [ '1' ],
               lorentz = [ L.FFV2, L.FFV3 ],
               couplings = {(0,0):C.GC_75,(0,1):C.GC_71})

and for the last I did find:

Cheers,

Olivier

Hi Olivier,
Maybe there is something wrong with my way of understanding？
In my opinion, the first are W-mu+n1 and W+e-n1, instead of W+e+n1. The second one is Ze-e+, instead of Ze-e-. The third one is W+e-ve~, instead of W-e-ve~.
Is my understanding wrong ？

Hi,

I guess that your issue is related to convention between particle and anti-particle.
I do not remember if in the UFO all particle are incoming or outcoming (I should check the UFO paper to know).
But in any case, a vertex (Z,e-, e-) would mean a vertex where the electric charge is not conserved according to the convention of the UFO paper. Is it really the type of vertex that you expect in your model?

Cheers,

Olivier

Hi Olivier,
I know that Ze-e - is charge nonconservative, which I believe deeply. But when I display diagrams, the vertex of Ze-e - does appear in one of the diagrams, and I also want to remove it. Do you have any good methods for this?

Olivier Mattelaer (olivier-mattelaer) said on 2022-11-15:

Hi,

Then I guess that the issue is more a display issue of the diagram than an issue with the model.
Your model does not have any Ze-e- interaction and those are not part of the computation.

I know some people are sometimes confused about Feynman Diagram with particle in T-channel.
For T-channel particle, the elecric charge that you assign to the T-channel particle depends of the fact that you consider particles are emitted or absorbed by the initial state.
Take for example e+ e- > ve ve~ via a T-channel W. Should you write "W+" or "W-" for the T-channel?
if you write W+, then you would have a "e+ W+ ve~" vertex and a "e- W+ ve" vertex.
but if you write a W-, then you would have a "e+ W- ve~" vertex and a "e- W- ve" vertex.
In both case, the "issue" is that the particle displayed are NOT in the UFO convention.

Cheers,

Olivier

Thank you very much for your answer！
By the way, there is another question: since the vertex in question does not appear in the UFO, I want to remove the diagrams containing the wrong vertex, but I cannot use /w - or /e -, because the diagrams I want to keep contains these particles. What else can I do?

Hi,

First, let me clarify that they are no wrong vertex. The vertex is perfectly fine.

So I would understand that you want to remove some Feynman Diagram (which is not the same are removing a vertex).
This is by nature something to do with caution since you can lead to unphysical result by doing so.
I have linked the associated FAQ.

Cheers,

Olivier
