"The Decay
Distributions of $\tau$ Produced by Neutrino-Nucleon
Scattering"
Abstract:
The decay of the $\tau$ produced by
neutrino-nucleon scattering
via charged
currents is studied for the decay modes,
$\tau\to\pi\nu,\ell\nu\bar\nu$.
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.
