Coupling Constants andSU(3)Classification of theY0*(1405)

Abstract

We present values for the $Y_0^{}{}_{}{}^{*}\mathrm{}\left(1405\right)\mathrm{}$ couplings to the $\overline{K}-N$ and $\pi -\Sigma$ channels. The relative sign is that appropriate to an $\mathrm{SU}\left(3\right)\mathrm{}$ singlet, but the relative magnitude differs by almost a factor of 3 from the corresponding $\mathrm{SU}\left(3\right)\mathrm{}$ prediction.
