Abstract: The limits on the parameters of thevμ→vτ oscillations are obtained in the E-564 hybrid experiment: Δm2≦4.5 eV2 and sin2(2θ)≦6.0·10−2 (90% CL). A possibility of direct observation of τ-lepton decays in the nuclear emulsion vertex detector allowed the sensitivity of this experiment to the parameters of the oscillations to be increased.
