Nuclear effects in (anti)neutrino charged-current quasielastic scattering at MINERνA kinematics

We compare the characteristics of the charged-current quasielastic neutrino and antineutrino scattering obtained in two different nuclear models, the phenomenological SuperScaling Approximation and the model using a realistic spectral function S(p, epsilon) that gives a scaling function in accordance with the (e, e') scattering data, with the recent data published by the MINER nu A Collaboration. The spectral function accounts for the nucleon-nucleon (NN) correlations by using natural orbitals from the Jastrow correlation method and has a realistic energy dependence. Both models provide a good description of the data without the need of an ad hoc increase of the value of the mass parameter in the axial-vector dipole form factor.
