Phys. Rev. C 60, 028201 (1999) [3 pages]Kaon photoproduction on the nucleon: Contributions of kaon-hyperon final states to the magnetic moment of the nucleonReceived 18 February 1999; published 6 July 1999 By using the Gerasimov-Drell-Hearn (GDH) sum rule and an isobaric model of kaon photoproduction, we calculate contributions of kaon-hyperon final states to the magnetic moment of the proton and the neutron. We find that the contributions are small. The approximation of σTT′ by σT clearly overestimates the value of the GDH integral. We find a smaller upper bound for the contributions of kaon-hyperon final states to the proton’s anomalous magnetic moment in kaon photoproduction, and a positive contribution for the square of the neutron’s magnetic moment. © 1999 The American Physical Society URL:
