Abstract: We investigate the helicity properties of the ejectile in quasielastic neutrino-induced nucleon-knockout reactions and consider the C-12 target as a test case. A formalism based on a relativistic mean-field model is adopted. The influence of final-state interactions is evaluated within a relativistic multiple-scattering Glauber approximation model. Our calculations reveal that the nucleon helicity asymmetries A(l) in quasielastic A(nu,N) and A((nu) over bar ,N) reactions are hardly affected by medium corrections, as final-state interactions and off-shell ambiguities in the electroweak current operators. On the contrary, the values of A(l) in A((nu) over tilde ,N) processes are extremely sensitive to strange-quark contributions to the weak vector form factors.
