Publication Abstract: The reaction gamma rho -> Kappa^+ Lambda(1520) using photoproduction data from the CLAS g12 experiment at Jefferson Lab is studied. The decay of Lambda(1520) into two exclusive channels, Sigma^+ pi^- and Sigma^- pi^+, is studied from the detected Kappa^+, pi^+, and pi^- particles. A good agreement is established for the Lambda(1520) differential cross sections with the previous CLAS measurements. The differential cross sections as a function of CM angle are extended to higher photon energies. Newly added are the differential cross sections as a function of invariant 4-momentum transfer t, which is the natural variable to use for a theoretical model based on a Regge-exchange reaction mechanism. No new N* resonances decaying into the Kappa^+ Lambda(1520) final state are found.
