| dc.description | Within the chiral soliton model the SU(3) breaking collective hamiltonian introduces representation mixing in the baryonic wave functions. We calculate ${\cal{O}}(m_s)$ effects of this mixing on the decay widths of decuplet and antidecuplet baryons. We find importance of the 27-plet admixture in the $Θ^+$ and $Ξ_{\bar{10}}$ decays. The role of the $1/N_c$ nonleading terms in ${\cal{O}}(m_s)$ transition matrix elements is discussed. | |
