Short-Range Correlations and Meson-Exchage Currents in Electron and Neutrino Scattering

Abstract: We investigate meson-exchange currents (MEC) in the one-particle emission transverse response of nuclear matter, incorporating short-range correlations via the Bethe-Goldstone equation with a realistic nucleon-nucleon interaction. The interference between one-body and two-body currents, strengthened by the high-momentum components of correlated pairs, produces a marked enhancement of the transverse response. We also indicate how the formalism extends to neutrino scattering, where similar effects are expected to impact oscillation experiments.
