Abstract
By using the Gerasimov-Drell-Hearn (GDH) sum rule and an isobaric model of kaon photoproduction, we calculate contributions of kaon-hyperon final stat es to the magnetic moment of the proton and the neutron. We find that the c ontributions are small. The approximation of sigma(TT') by sigma(T) 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 anomalo us magnetic moment in kaon photoproduction, and a positive contribution for the square of the neutron's magnetic moment.
