Vector meson dominance model and its application 矢量介子主导模型及其应用
As shown by the early experiments, electromagnetic form factors of nucleons which depend on momentum transfer can be well characterized by the dipole formula; the possible origin for this dipole formula has been interpreted in the framework of vector meson dominance model ( VMD ) theoretically. 早期的实验结果显示,核子的电磁形状因子对动量转移的依赖关系可以用偶极经验公式很好的描述,理论上用矢量介子主导模型对这一公式的物理起源进行了解释。
