Elastic Scattering of Neutrinos off Polarized Electrons
We calculate the cross sections for elastic nu_l + e^- --> nu_l + e^-
and antinu_l + e^- --> antinu_l + e^- scattering (l=e, mu or tau) in
the Born approximation and with exactly fixed polarization states of
target and final-state electrons, discussing their sensitivity to the
incident (anti)neutrino flavor. We suggest investigation of the flavor
composition of a (anti)neutrino beam by a flux-independent analysis of
the scattering of its constituents off polarized electrons.
