Abstract

The photoproduction of the Λ^*(1520) off both protons and neutrons in deuterium has been studied using the CLAS eg3 run data. The reactions are γ d → K⁺ Λ^* (n) and γ d → K⁰ Λ^* (p). Preliminary Λ^*(1520) cross sections and decay angle distributions are extracted in the photon energy region 1.75 GeV < E_γ < 5.50 GeV. This is the first time that exclusive photoproduction of Λ^*(1520) on neutrons has been reported. Moreover our results on protons extend to higher energies than the previous studies.
