Quantum-mechanical aspects of SU(3) Skyrme model in collective-coordinate quantization
We extend the quantization procedure on a curved space, applied already to the SU(2) Skyrme model, to the SU(3) case, and examine its quantum-mechanical structures in the framework of the collective-coordinate formalism. We assume existence of an SU(2) classical solution of the hedgehog type, which is embedded in the SU(3) solution. Then we have to treat the coset manifold SU(3)/U(1)/sub Y/, which is parametrized by a set of seven real parameters q/sup b/'s. The Wess-Zumino-Witten term is taken to be the symmetrized form of the well-known topological contribution to the effective Lagrangian L(q,q-italic-dot). From the starting Skyrme Lagrangian with time derivatives, two kinds of terms with order (h/2..pi..)/sup 2/ appear: one is independent of q/sup b/'s and gives a new contribution to the Skyrmion mass, and the other depends on q/sup b/'s through vielbeins in the q/sup b/-manifold. The former term plays a role to stabilize the rotating chiral soliton; while, the latter disappears in L(q,q-italic-dot) when expressed in terms of the covariant kinetic term, leaving a new mass contribution with negative sign. A comment is given concerning the Hamilton equations of motion and the quantum Euler-Lagrange equation.
