Photoproduction of K^*+¿¿/¿¿⁰ and K⁰¿¿⁺ from the Proton Using CLAS at Jefferson Lab

This dissertation presents measurements of the differential and total cross sections of the photoproduction ¿¿ + p → K^*+ + ¿¿ and ¿¿ + p → K^*+ + ¿¿⁰ using the CLAS g11a data collected at experimental Hall-B, Jefferson Lab. These measurements are the world’s first high statistics measurements of K^*+¿¿ and K^*+¿¿⁰ photoproduction. The cross section covers the incident photon energy range from 1.75 GeV to 3.85 GeV for K^*+¿¿ and from 1.85 GeV to 3.75 GeV for K^*+¿¿⁰ in the CLAS lab frame, Also, the ¿¿ recoil polarization of the K^*+¿¿ reaction channel is measured. The differential cross sections of ¿¿ + p → K⁰ + ¿¿⁺ were measured as a calibration reaction and those results are compared with the previous CLAS, SAPHIR and CBELSA measurements. The K^*+¿¿ recoil polarization was calibrated by checking the K⁺¿¿ polarization and comparing with previous CLAS measurements.
