Cross-section decreasing with increase in uncorrelated coupling
Asked by
Lopamudra Mukherjee
Dear MadGraph team,
I have a model in which I am looking at pp collision leading to a final state of tauons along with missing energy via some BSM fermion. This process should be independent of coupling between the BSM particle with muons. However, when I am changing this coupling, the cross-section is decreasing (which should not be the case, because it is independent of the muon coupling). The process is following :
MG5_aMC> generate p p > ttl- TTl+ , (ttl- > ta- h2 ) , (TTl+ > ta+ h2)
ttl-/TTl+ are the BSM fermions and h2 is the BSM scalar.
I am unable to resolve this issue. Please help!
Thank you.
