Abstract：
Exotics belong to high multiplet of SU(3), so one can understand them by researching their non-exotic partners in the same multiplet. Here the possible 27-plet from flavor SU(3) symmetry are investigated. By fitting the mass spectrum and calculating the two-body partial hadronic decay widths of members, two set of 27-plet baryons with different parities are found. For the mass spectrum, all non-exotic members have their candidates in PDG except for a new Λ(1780). For the decay widths, the computing results show the approximate flavor SU(3) symmetry. The further analyzing and comparing with the results from other theoretical models can support the rationality of the 27-plet assignment.
