Abstract:
The momenta of τ\tau decay products in the reaction e +e τ +τ e~+e~-\to\tau~+\tau~- do not constrain the τ\tau direction unambiguously. It is shown how the measurement of tracks of hadrons from semileptonic τ\tau decays, in particular their relative impact parameters, allows to resolve this ambiguity.
