Inclusive electron scattering within the SuSAv2 meson-exchange current approach
We present our recent progress on the relativistic modeling of electron-nucleus reactions and compare our predictions with inclusive ¹²C (e, e′) experimental data in a wide kinematical region. The model, originally based on the superscaling phenomenon shown by electron-nucleus scattering data, has r...

| description | We present our recent progress on the relativistic modeling of electron-nucleus reactions and compare our predictions with inclusive ¹²C (e, e′) experimental data in a wide kinematical region. The model, originally based on the superscaling phenomenon shown by electron-nucleus scattering data, has recently been improved through the inclusion of relativistic mean field theory effects that take into account the enhancement of the quasielastic transverse scaling function compared with its longitudinal counterpart. In this work, we extend the model to include the complete inelastic spectrum—resonant, nonresonant and deep inelastic scattering. We also discuss the impact of meson-exchange currents through the analysis of two-particle two-hole contributions to electromagnetic response functions evaluated within the framework of the relativistic Fermi gas, considering for the first time not only the transverse but also the longitudinal channel. The results show quite good agreement with data over the whole range of energy transfer, including the dip region between the quasielastic peak and the Δ resonance. |
