The $ϕ\to K^+K^-,K^{0}_{L},K^{0}_{S},K^{0}\bar K^0$ decays are studied using the method of phenomenological chiral Lagrangians. Calculated values for partial widths for these decay channels are compared with available experimental data.
The $ϕ\to ωπ^0$ decay is studied using the method of phenomenological chiral Lagrangians. It is shown that the weak hadronic current between $ω$-and $π^0$ -mesons is equal to zero and this decay channel proceeds only due to the $ϕ-ρ$ mixing diagram.
The τ\to (a_1 h)^- ν_τ decays of the τ-lepton are studied using the method of phenomenological chiral Lagrangians. The expression of weak hadronic currents between pseudoscalar and axial-vector meson states is obtained. Calculated partial widths for these decays are compared with the available experimental data.
The τ\to ω,ϕπ^- ν_τdecays of the τlepton are studied using the method of phenomenological SU(3) * SU(3) chiral Lagrangians. It is shown that the obtained value for the τ\to ϕπν_τdecay probability is very sensitive to deviations from the mixing angle. Calculated partial widths for these decays are compared with the available experimental and theoretical data.
