Relativistic descriptions of final-state interactions in neutral-current neutrino-nucleus scattering at MiniBooNE kinematics

The analysis of the recent neutral-current neutrino-nucleus scattering cross sections measured by the MiniBooNE Collaboration requires relativistic theoretical descriptions also accounting for the role of final-state interactions. In this work, we evaluate differential cross sections with the relativistic distorted-wave impulse approximation and with the relativistic Green's function model to investigate the sensitivity to final-state interactions. The role of the strange-quark content of the nucleon form factors is also discussed.
