Description

Precise modeling of neutrino (and electron) interactions on nuclear targets is essential for neutrino oscillations experiments. The modeling the energy of final state leptons and nucleons in quasielastic scattering on bound nucleons requires knowledge of both the removal energy of the bound nucleon as well as the Coulomb and nuclear optical potentials for the final state nucleon in the field of the spectator (A-1) nucleus. We compare the values of the optical potential for final state protons extracted from electron scattering data on nuclear targets in the quasielastic region to the extracted values of the optical potential for $\Delta$ resonances in the final state. This is the first measurement of the optical potential for the $\Delta$ resonance. We find that the optical potential for a $\Delta$ resonance in the final state is larger than the optical potential for a final state proton.
