====== TTP93-14 Tau Kinematics from Impact Parameters ======
 
 
<hidden TTP93-14  Tau Kinematics from Impact Parameters > The momenta of $\tau$ decay products in the reaction
 $e^+e^-\to\tau^+\tau^-$ do
 not constrain the $\tau$ direction unambiguously.  It is shown how
 the measurement of tracks of hadrons from semileptonic $\tau$
 decays, in particular their relative impact parameters, allows to
 resolve this ambiguity.
