The scattering of leptons on carbon and calcium targets are analyzed using an approach that incorporates the contributions to the nuclear response functions from the quasi-elastic (QE), inelastic process (RES), and two-particle and two-hole meson exchange current (2p-2h MEC). This RDWIA+MEC+RES approach is successfully tested against 12 C(e,e’) and 40 Ca(e,e’) scattering data. A fit of the RDWIA+MEC approach to the MiniBooNE neutrino data is performed and the best fit value of nucleon axial mass M A = 1.2 GeV is obtained. The flux-integrated CCQE-like differential cross sections for neutrino scattering at energies of the NOvA experiment are estimated.
The RDWIA+MEC+RES model is able to reproduce the (e,e') data and the MiniBooNE data with M_A=1
