CONSTRAINTS ON T-ODD AND P-EVEN HADRONIC-INTERACTIONS FROM NUCLEON, NUCLEAR, AND ATOMIC ELECTRIC-DIPOLE MOMENTS

We deduce constraints on time-reversal-noninvariant (TRNI), parity-conserving (PC) hadronic interactions from nucleon, nuclear, and atomic electric dipole moment (EDM) limits. Such interactions generate EDM's through weak radiative corrections. We consider long-range mechanisms, i.e., those mediated by meson exchanges in contrast with short-range two-loop mechanisms. We find that the ratio of typical TRNI, PC nuclear matrix elements to those of the strong interaction are less than or similar to 10(-5), a limit about 2 orders of magnitude more stringent than those from direct detailed balance studies of such interactions. This corresponds to a bound of \($) over bar g(rho)\ less than or similar to 10(-3) where ($) over bar g(rho), is a TRNI PC rho NN coupling.
