Abstract:

Applying the quark model of photoproduction, we predict a number of relations between the spin density matrix elements of the vector-mesons V0 produced via γB →V0B′ by polarized photons. The quark-model relations are compared with the experimental data obtained at SLAC for γp →ρ0p, γp →ωp and γp →φp at Eγ = 2.8, 4.7 and 9.3 GeV. The agreement of the quark-model predictions with the experimental data measured in the helicity system is very good for γp →ρ0p. For reactions γp →ωp and γp →φp, the agreement is good on the whole at three different values of energies over wide |t| region.
