dc.description.abstract We study the photon induced Lambda(1520) production in the effective Lagrangian method near threshold, E(gamma)(LAB)<= 2 GeV, and in the quark-gluon string model at higher energies 3 GeV <= E(gamma)(LAB)<= 5 GeV. In particular, we study the role of the K(*) exchange for the production of Lambda(1520) within the SU(6) Weinberg-Tomozowa chiral unitary model proposed by Garcia-Recio, Nieves, and Salcedo [Phys. Rev. D 74, 034025 (2006)]. The coupling of the Lambda(1520) resonance to the N (K) over bar* pair, which is dynamically generated, turns out to be relatively small and, thus, the K exchange mechanism dominates the reaction. In the higher energy region, where experimental data are available, the quark-gluon string mechanism with the K Regge trajectory reproduces both the energy and the angular distribution dependences of the Lambda(1520) photoproduction reaction.
