Density dependence of 2p-2h meson-exchange currents
Density dependence of 2p-2h meson-exchange currents
We analyze the density dependence of the contribution of meson-exchange currents to the lepton-nucleus inclusive cross section in the two-particle two-hole channel. The model is based on the relativistic Fermi gas, where each nucleus is characterized by its Fermi momentum ${k}_{F}$. We find that the 2p-2h nuclear response functions at …
