Abstract

By treating the new vectoc meson resonances discovered at DCI as q q excitations, we stress that the experimental result Γ tot ( ω n )⪡ Γ tot ( ϱ n ) and different branching ratios into multipion states present a paradoxical situation. Using quark pair creation model, we try to resolve this through large 1 3 D 1 mixing, implying dominant ϱ n decay via π A 1 channel .
