Evidence is accumulating for the existence of some new hyperon resonances, such as a $\\Sigma^*$ of spin-parity $J^P=1/2^-$ around 1400 MeV instead of 1620 MeV as listed in PDG, a new $\\Sigma(1540)3/2^-$ resonance, a new narrow $\\Lambda(1670)3/2^-$ resonance and a new $\\Lambda(1680)3/2^+$ resonance. All these new hyperon resonances fit in the predicted pattern of the unquenched quark models very well. It is extremely important to check and establish the spectrum of these low ","authors_text":"B.
