Syntax for VBF

Asked by R

So I need to produce V+ via VBF for a model I am using.

So the signal that I need looks like this -

q q > w+ z j j

Then the w+ z fuses to produce a V+.

What would the syntax be like for such a process?

Hi,

I guess that it should be something like
generate p p > v+ j j QCD=0

but please check the Feynman Diagram.

Cheers,

Olivier

Hi,
So this produced 112 processes and 2312 diagrams. However, I am only interested in a few.
I know it is a bad idea to exclude using '/d' or '/s' as it violates gauge invariance.
Is there a way I can directly input the diagrams?

Never mind, I found the solution from another post.
Thanks!!
