abstract
We investigate the hyperon semileptonic decay constants, $f_2/f_1$, and $g_1/f_1$, within a general framework of a chiral soliton model. All relevant parameters for the SU(3) baryon wave functions were unambiguously determined by using the experimental data for the masses of the baryon octet and the decuplet. Using then the existing experimental data for the magnetic moments of the baryon octet and the decay constants of hyperon semileptonic decays, we are able to determine all the hyperon semileptonic decay constants $f_2/f_1$ and $g_1/f_1$ of the baryon octet unequivocally. In addition, we also present the results of the axial-vector transition constants from the baryon decuplet to the octet.

Flavor SU(3) analysis of the charmless semileptonic $B \to PV\ell^+\nu_\ell$ decays
The paper predicts branching ratios of charmless B to PV l nu decays mediated by axial-vector, tensor, and excited vector resonances using SU(3) flavor symmetry, finding several modes at 10^-4 to 10^-3.

Pentaquarks and Maxim V. Polyakov
A review argues that Diakonov-Petrov-Polyakov's narrow-width Theta+ pentaquark prediction remains viable, identifying N*(1685) as the antidecuplet partner and citing LEPS/DIANA data as support.

Odyssey of the elusive $\Theta^+$
A review of the Theta+ pentaquark story concludes that the chiral soliton model's small-width prediction remains viable and new kaon-beam experiments may decide its existence.
