Extraction of the ¹²C Longitudinal and Transverse Nuclear Electromagnetic Response Functions from all Electron Scattering Measurements on Carbon

We report on an extraction of the ¹²C Longitudinal (R_L) and Transverse (R_T) 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 (02<0.5 GeV²). We extract R_L and R_T as a function of ν for both fixed values of Q² as well fixed values momentum transfer q. The data sample consists of more than 10,000 ¹²C differential electron scattering and photoproduction cross section measurements. Since the extracted response functions cover a large range of Q² and ν, they can be used to validate nuclear models as well Monte Caro generators for electron and neutrino scattering experiments.
