CP-violating decays of the pseudoscalars eta and eta' and their connection to the electric dipole moment of the neutron

Thomas Gutsche, Astrid N. Hiller Blin, Sergey Kovalenko +4

Using the present upper bound on the neutron electric dipole moment, we give an estimate for the upper limit of the CP-violating couplings of the eta(eta') to the nucleon. Using th…
