摘要：
Within the chiral soliton model the SU(3) breaking collective Hamiltonian introduces representation mixing in the baryonic wave functions. We calculate O(m(s)) effects of this mixing on the decay widths of decuplet and antidecuplet baryons. We find importance of the 27-plet admixture in the Theta(+) and Xi-(10) decays. The role of the 1/N-c nonleading terms in O(m(s)) transition matrix elements is discussed.
