The reaction e^→pe′K⁺Λ(1520) with Λ(1520)→p′K⁻ was studied at electron beam energies of 4.05, 4.25, and 4.46 GeV, using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cos θ_K+, φ_K+, Q², and W dependencies of Λ(1520) electroproduction are presented for the kinematic region 0.9 < Q² < 2.4 GeV² and 1.95 < W < 2.65 GeV. Also, the Q² dependence of the Λ(1520) decay angular distribution is presented for the first time. The cosθ_K+ angular distributions suggest t-channel diagrams dominate the production process. Fits to the Λ(1520) t-channel helicity frame decay angular distributions indicate the m …
