标题： Kaon photoproduction on the nucleon: Contributions of kaon-hyperon final states to the magnetic moment of the nucleon

摘要： 通过使用Gerasimov-Drell-Hearn（GDH）求和规则和介子模型的K介子光生反应，我们计算了K介子-超子末态对质子和中子磁矩的贡献。 我们发现这些贡献很小。 将sigma_{TT'}近似为sigma_{T}明显高估了GDH积分的值。 我们在K介子光生反应中发现了K介子-超子末态对质子异常磁矩的贡献的较小上限，并发现中子磁矩平方有正贡献。 显示英文摘要

摘要： 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 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 anomalous magnetic moment in kaon photoproduction, and a positive contribution for the square of the neutron's magnetic moment.
