The contributions of the vector leptoquarks of Pati–Salam type to the branching ratios of [Formula: see text] decays are calculated with account of the fermion mixing in the leptoquark currents of the general type. Using the general parametrizations of the mixing matrices the lower vector leptoquark mass limit [Formula: see text] [Formula: see text] 86 TeV is found from the current experimental data on these decays. The branching ratios of the decays [Formula: see text] predicted at [Formula: see text] = 86 TeV are calculated. These branching ratios for the decays [Formula: see text] are close to the experimental data whereas those for the decays [Formula: see text] and [Formula: see text] are by order of 2–4 less than their current experimental limits. For the decays [Formula: see text] these branching ratios are of orders [Formula: see text] and [Formula: see text], respectively. The predicted branching ratios will be useful in the current and future experimental searches for these decays.
