  In this paper we study the influence of nuclear medium effects on
quasi-elastic neutrino-nucleus scattering processes. We focus on effects
provided by the nuclear mean field and random phase correlations and pay
special attention to differences between neutrino- and antineutrino-induced
reactions. We confront our results with the T2K and MiniBooNE data for both
neutrinos and antineutrinos and the neutrino-antineutrino asymmetry. In view of
the recently published ab initio results we provide a careful comparison
between our cross section predictions and the ab-initio calculations.
