Description
We use the chiral quark soliton model to estimate masses and widths of the two eikosiheptaplets (27-plets of SU(3) flavor) of spin 3/2 and 1/2 that emerge in the rigid rotator quantization. We use as input: hyperon decays, Θ+ mass, and width. While 273/2 has small widths (although much larger than the values allowed by the partial wave analysis), 271/2 has large decay widths to antidecuplet. However, exactly for this decay channel the widths are suppressed in the large Nc limit
