Description
A reasonable understanding of the smallness of the rho'->ππ- to the rho'->rhoππ branching ratio in the context of the quark-pair creation model (QPCM) is achieved. Our crucial hypothesis consists in assuming that the rho can be phenomenologically considered as a gauge particle which couples to the derivative rho'ππ coupling through a gauge principle. This fixes unambiguously the rho'->rhoππ amplitude. (orig.)
