Nucleon magnetic form factors with non-local chiral effective Lagrangian

Abstract

Chiral perturbation theory is a powerful method to investigate the hadron properties. We apply the non-local chiral effective Lagrangian to study nucleon magnetic form factors. The octet and decuplet intermediate states are included in the one loop calculation. With the modified propagators and non-local interactions, the loop integral is convergent. The obtained proton and neutron magnetic form factors are both reasonable up to relatively large $Q^2$.Comment: 11 pages, 7 figures, 1 tables. arXiv admin note: text overlap with arXiv:1210.507
