| dc.description.abstract | We examine the associative photoproduction of Roper resonance with vector mesons, γ +N—>N* ( 1440)+V. in the near threshold region by using the analogy with the processes of “elastic” vector meson photoproduction, γ +N—>N+V. Different production mechanisms are suggested. In addition to standart α- and π-exchanges in the t-channel, the baryonic exchanges in the s- and u-channel are taken into account as well. We calculate the differential cross-section and beam asymmetry on proton and neutron targets for the reaction γ+N—>N*(1440)+ω. All calculations are performed at Eγ,= 2.5 GeV. The recent study [1] on the associative photoproduction o f Roper resonance with vector mesons, γ+N —>N*(1440)+V, in the near threshold region indicates the importance of the pseudoscalar (π) exchange for t-channel in associative ω-meson photoproduction but it does not give a clear information about the relative role of different possible threshold mechanisms on the production o f N*(1440). Therefore, in additon to standart G- and δ-exchanges in the t-channel, we consider the baryonic resonances in the s- and u-channel . For t-channel, the pseudoscalar (π) and scalar exchanges ( δ ), Fig. 1(a), are considered The pseudoscalar exchange amplitude can be obtained from the Lagrangian,.... | tr_TR |
