Description

If a true width of the resonance δ is large, as it is usual for δ in the qq-bar and q2q-bar2 models, the data on the process γγ → δ → ηπ testify to preference of the magnitude Γδγγ(mδ)=1.3 keV perdicted by qq-bar model as compared with the value Γδγγ < 1 keV predicted in the framework of the q2q-bar2 model
