摘要：
In this Letter we investigate an SU(3) extension of the axially symmetric B = 2 chiral quark soliton model The classical soliton is extended to the SU(3) by trivial embedding. We expand the quark determinant in terms of the: collective angular velocity up to the second order and the quark mass difference of the first order. The mass spectrum and the binding energy of the baryon-baryon channels down to strangeness S = -6 are then obtained. (C) 2002 Elsevier Science B.V. All rights:reserved.
