On the width of the Δ(1232) in NΔ and ΔΔ states
Due to the finite kinetic energy in the intermediate NΔ state the (internal) energy available for mesonic decay is decreased and consequently the effective NΔ width is suppressed in NN scattering. The same can happen also in ΔΔ case. Also the NΔ angular momentum suppresses the width as well, while t...
