Theta-Induced Electric Dipole Moment of the Neutron via QCD Sum Rules
M. Pospelov, A. Ritz
Abstract
Using the QCD sum rule approach, we calculate the electric dipole moment of the neutron induced by a vacuum theta--angle to approximately 40-50% precision, dn = 2.4 x 10-16 θe.cm. Combined with the new experimental bound, this translates into the limit |θ|< 3 x 10-10.
