The branching fractions of the decays [Formula: see text], [Formula: see text] and [Formula: see text] are calculated in the framework of the extended [Formula: see text] chiral Nambu–Jona-Lasinio model. There are no experimental data for these decays in the present time, thus the obtained results are considered as predictions. The comparison of these results to the theoretical results of other authors is carried out.
