The contributions of the chiral gauge leptoquarks [Formula: see text] induced by the chiral four-color quark–lepton symmetry to the branching ratios of [Formula: see text] decays are calculated and analyzed using the general parametrizations of the fermion mixing matrices in the leptoquark currents. From the current experimental data on these decays under assumption [Formula: see text], the lower mass limit [Formula: see text] is found, which in particular case of equal gauge coupling constants gives [Formula: see text]. The branching ratios of the decays under consideration predicted by the chiral gauge leptoquarks are calculated and analyzed in dependence on the leptoquark masses and the mixing parameters. It has shown that in consistency with the current experimental data, these branching ratios for [Formula: see text] decays can be close to their experimental limits and those for [Formula: see text] decays can be of order of [Formula: see text]. The calculated branching ratios will be useful in the further experimental searches for these decays.
