The existence of etamesic nuclei has been speculated for a long time without firm experimental evidence. Much of the effort has taken place in final state interactions on production. One crucial factor in seeing a quasibound state is its width, which should be related to the imaginary part of the scattering length. Comparing two models for ηN scattering giving the same elementary scattering length, a simple optical potential and an explicit coupling to the pionic channel, it is seen that the…

Problems in theoretical physics often lead to paradoxical answers; yet closer reasoning and a more complete analysis invariably lead to the resolution of the paradox and to a deeper understanding of
