Axial current matrix elements of the nucleon based on an exact diagonalization of the SU(3) Skyrme model hamiltonian
Description
The vanishing of the form factor of the SU(3) single axial current is shown to be stable under the addition of derivative type symmetry breaking terms in the SU(3) Skyrme model. We find that treating the collective hamiltonian exactly dramatically lowers the predicted form factor for the strange quark axial current. Nevertheless, agreement with the EMC experiment is maintained. (orig.)
