Tau lepton polarization in quasielastic neutrino-nucleon scattering
arXiv:hep-ph/0408107 · doi:10.1016/j.nuclphysbps.2004.11.221
Abstract
We derive structure functions for the quasielastic production of octet baryons in neutrino and antineutrino interactions with nucleons and study the polarization of tau leptons produced in the reactions. Possible impact of the charged second-class currents is investigated by adopting a simple phenomenological parametrization for the nonstandard scalar and tensor nucleon form factors. Our choice of the unknown parameters is made to satisfy the limits obtained in the (anti)neutrino scattering experiments and rigid restrictions derived from the nuclear structure studies.
