How to consider the coupling of different intermediate state processes
Asked by
zxy
Now I have considered two processes. Except for the propagator in the middle, the initial state particles and the final state particles are exactly the same. My production process is as follows:
define n = n1 n2
generate e- e+ > n ve~ , ( n > w+ e-, w+ > c s~)
Where n is the heavy neutrino, which is the particle of the new physical model defined by feynrules.
However, in the process of generating with this statement, the image madgrah corresponding to different n does not interfere. I want the two processes to interfere. What should I do?
