"Web5. Except for small electromagnetic decay branching ratios like Δ → N γ, essentially 100% of the branching ratio of the Δ is to N π final states. This is just kinematics. The only other hadronic final state with baryon number one that is energetically allowed is N π π, which has an extremely small phase (it is just barely allowed). " - Branching decay
