Abstract

We calculate {eta}d elastic scattering using a relativistic three-body model with separable interactions in order to study the position of the quasivirtual {eta}NN state in the complex plane. The inputs of the model are the separable potentials of the NN and mN subsystems, where m is a meson (m={eta},{pi}, or {sigma}). {sigma} is not treated as a stable particle but as a {pi}{pi} resonance so that we include its mass and width as deduced from the phase shift of the I=J=0 resonance. In all cases, we find that the nearest pole corresponds to a quasivirtual state even if Re A{sub {eta}}{sub d} is negative.
