Investigation of single and double polarization observables for associative photoproduction of vector mesons and baryon resonances using effective Lagrangian approach

mesons ( ρ and ω ) and baryon resonances (N*(1440) and N*(1710)) on nucleons neardσ dt and doublethreshold energy. We predicted via this model, differential cross sectionspin polarization observables with respect to momentum transfers for the reactionsγ + N → ω + N * (1440)γ + N → ρ + N * (1440) = 2.5GeV ,at Eγandγ + N → ρ + N * (1710) γ + N → ω + N * (1710) = 3.25GeV . The calculationsat Eγandπ σ ηare limited by and exchanges in the t-channel (including for N*(1710)), the neutralω (782)),vector mesons with the lower energies ( ρ (770) and low momentum transfers andnear threshold energy.Key Words: N*(1440) , N*(1710), Vector Meson Photoproduction, Differential Cross Section,Double Spin Polarization Observable, Omega mesons, Sigma mesons, Rho mesons.
