Photoproduction of ρ- and ω-mesons in the peripheral model

Photoproduction of ρ- and ω-mesons on nucleons is considered. The possible matrix elements according to the peripheral model are constructed and the cross section is calculated, π, η, σ ( ABC) and vector meson exchange is taken into account. The angular distribution for the decay pions of polarized ρ's is discussed with particular reference to peripheral production
