Abstract The photoproduction of Φ and J/ψ meson off the nucleon is investigated within a dynamical model approach based on a Hamiltonian which describes the reaction mechanisms of the Pomeron exchange, meson exchange, and direct Φ- or J/ψ-radiation terms. The final state interaction is described by the gluon-exchange and direct Φ- or J/ψ-N coupling terms. The parameters of the Hamiltonian are determined by the latest experiments at the Jefferson Laboratory (JLab). We have found that the t-channel light mesons play a crucial role to describe the available JLab data in the low-energy region.
