Sažetak
The broad importance of a recent experimental discovery of pentaquarks requires more theoretical insight into the structure of higher representation multiplets. The nucleon axial-vector coupling, moments of inertia, the 8, 10, (10) over bar, and 27(3/2) absolute mass spectra and the higher SU(3)(f) representation mass splittings for the multiplets 8, 10, 10, 27, 35, 35, and 64 are computed in the framework of the minimal SU(3)(f) extended Skyrme model by using only one free parameter, i.e., the Skyrme charge e. The analysis presented in this paper represents simple and clear theoretical estimates, obtained without using any experimental results for higher ((10) over bar, ...) multiplets. The obtained results are in good agreement with other chiral soliton model approaches that more extensively use experimental results as inputs.
