"The Decay Distributions of $\tau$ Produced by Neutrino-Nucleon


                                      Kentarou Mawatari


  The decay of the $\tau$ produced by neutrino-nucleon scattering

via charged currents is studied for the decay modes,


  In this talk, we show the energy and angular distributions

of the decay particles from the $\tau$, considering the $\tau$

polarization in neutrino-nucleon scattering, for the $\nu_\tau$

appearance experiments in the CERN-to-Gran Sasso project, and

show that the decay particle distributions are significantly affected

by the $\tau$ polarization.
