摘要：

We calculate the neutron electric dipole form factor induced by the CP-violating theta term of QCD within a perturbative chiral quark model which includes pion and kaon clouds. On this basis, we derive the neutron electric dipole moment and the electron-neutron Schiff moment. From the existing experimental upper limits on the neutron electric dipole moment, we extract constraints on the theta parameter and compare our results with other approaches.
