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.
