Nucleon electromagnetic form factors in hidden local symmetry theory

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

In previous papers (Nuovo Cimento A,108 (1995) 241, 1051), the hidden local symmetry of the chiral theory based on the non-linear sigma-model on the manifoldU(3)L×U(3)R/U(3)V was extended to the baryon interaction and shown to reproduce well the low-energy theorems. Introducing anSU(3) breaking in the theory, the mass formula and the Sakurai formula of the electromagnetic interaction of vector mesons are obtained consistently. In this paper, by introducing the effective tensor interactions of orderO(p 2), the magnetic form factor of the nucleon is analysed as well as the electric form factor, partly done in the previous papers, and a breaking of the OZI rule and a sizeable content of s-quark pair in both the electric and magnetic form factors of the nucleon are indicated again.
