- W1996553739 abstract "We examine the effects of pseudoscalar and pseudovector coupling of the $ensuremath{pi}$ and $ensuremath{eta}$ mesons in one-boson exchange models of the $mathrm{NN}$ interaction using two approaches: time-ordered perturbation theory unitarized with the relativistic Lippmann-Schwinger equation, and a reduced Bethe-Salpeter approach using the Thompson equation. Contact terms in the one-boson exchange amplitudes in time-ordered perturbation theory lead naturally to the introduction of s-channel nucleonic cutoffs for the interaction, which strongly suppresses the far off-shell behavior of the amplitudes in both approaches. Differences between the resulting $mathrm{NN}$ predictions of the various models are found to be small, and particularly so when coupling constants of the other mesons are readjusted within reasonable limits." @default.
