Positivity constraints for lepton polarizationin neutrino deep inelastic scattering
Résumé
We consider the spin polarization of leptons produced in neutrino and antineutrino nucleon deep inelastic scattering, via charged currents, and we study the positivity constraints on the spin components in a modelindependent way. These results are very important, in particular in thecase of $\tau^{\pm}$ leptons, because the polarization information is crucialin all future neutrino oscillation experiments.
