We re-analyze the predictions of chiral-soliton models for the masses and decay widths of baryons in the exotic antidecuplet of flavour SU(3). The calculated ranges of the chiral-soliton moment of inertia and the π-nucleon scattering ΣπN term are used together with the observed baryon octet and decuplet mass splittings to estimate 1430 MeV < mΘ+ < 1660 MeV and 1790 MeV < mΞ−− < 1970 MeV. These are consistent with the masses reported recently, but more precise predictions rely on ambiguous… Expand
