Positivity constraints for lepton polarization in neutrino deep inelastic scattering
Abstract
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 model independent way. These results are very important, in particular in the case of τ leptons, because the polarization information is crucial in all future neutrino oscillation experiments.
