Associative Photoproduction of Roper Resonance and ω-Meson
Associative photoproduction of ω-meson and N∗(1440) on nucleons, γ + N → ω + N∗(1440), in the near threshold region is investigated in a framework employing effective Lagrangians. Besides π-exchange in t-channel, baryon exchanges, i.e. Nand N∗-exchanges, in the sand u-channels are also taken into account in calculations of differential cross-section and beam asymmetry. Important inputs of this ...
متن کاملexcitations and “ missing resonances ” in the ω meson photoproduction
In this work, an improved quark model approach to the ω meson photoproduction with an effective Lagrangian is reported. The t-channel natural parity exchange is consistently taken into account through the Pomeron exchange, while the unnatural parity exchange is described by the π 0 exchange. It shows that with very limited number of parameters, all the available experimental data in the low ene...
متن کاملω-Meson Photoproduction on Nucleons In the Near Threshold Region
The ω-meson photoproduction, γ+p → p+ω, is studied in the framework of a model, containing π-meson exchange in t-channel and nucleon-exchange in sand u-channels. Considering both ωNN -coupling constants in the region of time-like meson four momenta as the free parameters, we find different sets of solutions for these constants from the existing data on the t-dependence of the differential cross...
متن کاملIn-medium properties of the ω meson through ω photoproduction in nuclei
The feasibility to study the in-medium properties of the ω meson in photon induced reactions on nuclei is investigated by means of a semiclassical transport model. The calculations are dedicated to an experiment presently being analyzed by the TAPS/Crystal Barrel collaborations. A full coupled-channel treatment of final state interactions allows a quantitative analysis of the influence of absor...
متن کاملVector Meson Photoproduction with an Effective Lagrangian in the Quark Model II: ω Photoproduction
An investigation of γp → ωp is presented in a constituent quark model approach. The sparse data in the large t region where the resonances dominate is well described within the model, while the diffractive behavior in the small t region requires an additional t-channel exchange. Taking into account the t-channel π exchange, we find a good overall agreement with the available data with only 3 fr...
