| 英文摘要 | Dirac and pauli form factors are investigated in the relativistic chiral effective lagrangian. the octet and decuplet intermediate states are included in the one-loop calculation. the 4-dimensional regulator is introduced to deal with the divergence. different from the non-relativistic case, this 4-dimensional regulator is generated from the nonlocal lagrangian with the gauge link, which guarantees local gauge invariance. as a result, additional diagrams appear which ensure electric charge 1 and 0 for proton and neutron respectively. the obtained dirac and pauli form factors of the nucleons are all reasonable up to relatively large q(2). |
