Relativistic description of final-state interactions in neutral-current
neutrino and antineutrino cross sections

We evaluate semi-inclusive neutral-current quasielastic differential neutrino and antineutrino cross sections within the framework of the relativistic impulse approximation. The results of the relativistic mean field and of the relativistic Green's function models are compared. The sensitivity to the strange-quark content of the nucleon form factor is also discussed. The results of the models are compared with the MiniBooNE experimental data for neutrino scattering. Numerical predictions for flux-averaged antineutrino scattering cross sections are also presented.
