    "abstract": "The electric dipole form factor of the nucleon stemming from the QCD\n$\\bar{\\theta}$ term is calculated in chiral perturbation theory in leading\norder. To this order, the form factor originates from the pion cloud. Its\nmomentum-dependence is proportional to a non-derivative time-reversal-violating\npion-nucleon coupling, and the scale for momentum variation--appearing, in\nparticular, in the radius of the form factor--is the pion mass.",
