Description
We report on a global extraction of the 12C Longitudinal (RL) and Transverse (RT ) nuclear electromagnetic response functions from an analysis of all available electron scattering dats on carbon. The response functions are extracted for a large range of energy transfer ν, spanning the nuclear excitation, quasielastic, and ∆(1232 MeV) region, over a large range of the square of the four-momentum transfer Q2. We extract RL and RT as a function of ν for both fixed values of Q2 (0 ≤ Q2 ≤ 1.5 GeV), as well fixed values of momentum transfer q. The data sample consists of more than 10,000 12C differential electron scattering and photo-absorption-cross section measurements. Since the extracted response functions cover a large range of Q2 and ν, they can be readily used to validate both nuclear models as well Monte Caro (MC) generators for electron and neutrino scattering experiments. The extracted response functions are compare to the prediction of several theoretical models and to predictions of the electron-mode versions of the NuWro and GENIE neutrino MC generators.
