Abstract

We present continuum random phase approximation calculations (CRPA) for neutrino-induced quasielastic scattering off atomic nuclei. The validity of our formalism is checked by a careful confrontation of its results with semi-inclusive double-differential electron scattering data. We pay special attention to excitations in the giant resonance region. The CRPA is well-suited for the description of interactions in this energy range. We aim at providing a uniform description of one-nucleon knockout processes over the whole energy range from threshold to the quasielastic peak. Our calculations point to the fact that low-energy and giant-resonance excitations provide a non-negligible contribution to the interaction strength, especially at forward lepton-scattering angles.

Highlights

  • Quasielastic scattering is an important reaction mechanism in accelerator-based neutrino-oscillation experiments

  • Hartree-Fock (HF) single-particle bound-states and the continuum wave functions are obtained by solving the Schrödinger equation using an effective Skyrme interaction

  • As evident from the results presented here, they can account for non-negligible contributions to the signal
