Abstract

The validity of vector-meson dominance is tested by comparing our high statistics $ρ^{0}$ and $ω$ production experiments at 2.7 and 4 GeV/c with the results of polarized photopion production experiments. Our results suggest the breakdown of the vector-dominance model even after taking into account the strong $S$ -wave $π π$ interaction in the $ρ^{0}$ region.
