Final-State Interactions Effects in in Neutral-Current Neutrino and Antineutrino Cross Sections at MiniBooNE Kinematics

The predictions of different relativistic descriptions of final-state interactions are compared with the neutral-current elastic neutrino- and antineutrino-nucleus differential cross sections recently measured by the MiniBooNE Collaboration. The results of the relativistic Green’s function model describe the data without the need to increase the standard value of the nucleon axial mass.
