Description
We have performed a global extraction of the 12C, 58Ca and 56Fe longitudinal (RL) and transverse (RT) nuclear electromagnetic response functions from an analysis of all available electron scattering data on these nuclei. The response functions are extracted for energy transfer spanning the nuclear excitation, quasielastic (QE), resonance and inelastic continuum over a large range of the square of the four-momentum transfer, Q2 In addition, we perform a universal fit to all 12C electron scattering data which also provides parmeterizations of RL and RT over a larger kinematic range. Given the nuclear physics common to both electron and neutrino scattering from nuclei, extracted response functions from electron scattering spanning a large range of Q2 and energy transfer also provide a powerful tool for validation and tuning of neutrino Monte Carlo (MC) generators. We compare the measurements to theoretical predictions and neutrino/electron MC generators.
