“…For an interesting dual amplitude model applied to πN scattering, which contains Regge asymptotic behavior for forward and backward angles and which shows resonance features at low energy, we refer to Ref. [30].…”

A reggeized model for η and η ′ photoproduction on the nucleon is presented. In this model, t-channel vector meson exchanges are described in terms of Regge trajectories to comply with the correct high energy behavior. We compare this reggeized model with an isobar model (η-MAID), where the t-channel exchanges are described by ρ and ω poles. Both models contain the same resonance contributions, and describe current γp → ηp data up to E lab γ = 2 GeV quite well, but only the reggeized model can be successfully extended to higher energies. For the γp → η ′ p reaction, the reggeized model is found to be able to give a satisfactory description. For the differential cross section data from SAPHIR, we find that the observed linear forward rise in cos θ near E lab γ = 1.6 GeV can be well described by the interference of an S 11 resonance and the Regge trajectory exchanges without any need for an additional P -wave resonance.

“…In the literature, the model has been applied to a variety of reactions [82][83][84]. In general, however, the "bare" Veneziano amplitude appears too restrictive to provide a realistic description of the production processes in the resonance region [75].…”

“…Nevertheless, the additional term in Eq. (5.12) can be considered as a characteristic feature of all dual models [84]. Therefore, we will use this prescription in the Regge formalism in order to introduce direct s-channel poles in a way that respects the duality between the (t-channel) Regge and the (schannel) resonance amplitude.…”
