Abstract: (APS)
We report measurements of ρ0 and ϕ electroproduction at 19.5 GeV in a wide-aperture spectrometer which detected the scattered electron and the decay products of the vector mesons. As |q2| increases, the ρ mass spectrum shape changes, the momentum-transfer distribution broadens, and the ratio of the ρ cross section to the total cross section decreases. The ratio of longitudinally to transversely polarized ρ0 mesons is 0.45−0.10+0.15 at |q2|=mρ2, and the interference between longitudinal and transverse amplitudes is almost maximal. The relative ϕ-meson cross section also decreases as |q2| increases.References(6)
