We present measurements of the differential cross section and 'B; recoil polarization for the γp → K⁺Λ reaction made using the CLAS detector at Jefferson Lab. These measurements cover the center-of-mass energy range from 1.62 to 2.84 GeV and a wide range of center-of-mass K⁺ production angles. Independent analyses were performed using the K⁺pπ⁻ and K⁺p (missing π⁻) final-state topologies; results from these analyses were found to exhibit good agreement. These differential-cross-section measurements show excellent agreement with previous CLAS and LEPS results and offer increased precision and a 300-MeV increase …
