Decay of neutral particle
Asked by
Maksym Ovchynnikov
I am simulating a process with
p p > h w+, w+ > e+ ve, (h > sp sp, (sp > mu+ mu-))
where sp is new real scalar particle.
I expect to see a diagram at which only one sp decays, however, it shows that two scalars decay. How to restrict MadGraph to decay only one of the scalars?
Or, at least, how to distinguish between mu- mu+ pair of one scalar and another one? Namely, if I would like to select the mu+ from the decay products, I need to adjust to it the mu-, and naively there is an ambiguity...
