Abstract
We studied the decay distributions of Ï leptons produced in neutrino-nucleon scattering via charged current interaction, taking into account the Ï polarization, for the long baseline neutrino oscillation experiments which aim to observe Î½Ï appearance. The information on the Ï polarization is essential for measuring Î½Ï appearance since the decay particle distributions depend crucially on the Ï spin. We show that Ï produced via neutrino has high degree of polarization, and its spin direction depends non-trivially on the energy and the scattering angle of Ï in the laboratory frame. We also show that the subsequent decay distributions are significantly affected by the produced Ï polarization.
