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.6 pages, No figures, LatexHigh Energy Physics - Phenomenologytext
