Abstract
The reaction 𝛾𝑝→𝐾+Λ(1520) using photoproduction data from the CLAS 𝑔12 experiment at Jefferson Lab is studied. The decay of Λ(1520) into two exclusive channels, Σ+𝜋− and Σ−𝜋+, is studied from the detected 𝐾+, 𝜋+, and 𝜋− particles. A good agreement is established for the Λ(1520) differential cross sections with the previous CLAS measurements. The differential cross sections as a function of center-of-mass angle are extended to higher photon energies. Newly added are the differential cross sections as a function of invariant four-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 𝐾+Λ(1520) final state are found.
