ABSTRACT

The next generation of neutrino-oscillation experiments are expected to bring definite answers to the neutrino-mass hierarchy and violation of charge-particle symmetry in neutrino oscillations. To achieve these goals it is, however, necessary to ensure a significant reduction of uncertainties, particularly those related to neutrino-energy reconstruction. As these measurements are going to be performed at the kinematics where the dominant mechanism of interaction is scattering off individual nucleons bound in nuclei, I will argue that it is highly improbable that theoretical approaches unable to reproduce (e,e') data would provide sufficient accuracy in neutrino interactions. I will show that nuclear effects can be accurately modeled in the spectral function approach, paying special attention to the importance of final-state interactions between the struck nucleon and the residual nucleus.
