The neutron EDM and bounds on rare decays of eta and eta-prime mesons

We complete our derivation of upper limits on the CP violating ηππ and η‘ππ couplings from an analysis of their two-loop contribution to the neutron electric dipole moment (nEDM). As a result we obtain numerical upper limits for the ηππ and η‘ππ branchings and couplings which are important for plann...
