摘要：

The evaluation, systematic analysis, and numerical study of the semileptonic tau-lepton decays with two mesons in the final state has been made in the frame of the standard model extended by right handed neutrinos. In the analysis, heavy-neutrino nondecoupling effects, finite quark masses, quark and meson mixings, finite widths of vector mesons, chiral symmetry breakings in vector-meson-pseudoscalar-meson vertices, and effective Higgs-boson-pseudoscalar-meson couplings have been included. Numerical estimates reveal that the decays tau(-)-->e(-)pi(-)pi(+),tau(-)-->e(-)K(-)K(+), and tau(+)-->e(-)K(0) (K) over bar(0) have branching ratios of the order of 10(-6), close to present-day experimental sensitivities.
