We study the 2p-2h contribution to the deep inelastic inclusive electron scattering by including both the meson exchange currents and the nucleon-nucleon correlations. A satisfactory agreement with the available experimental data is achieved. In the same frame p-wave pion absorption at threshold is also examined; it is shown that a strong quenching is required to account for the π-nucleus absorptive potential deduced from pionic atoms data. Finally the conditions are explored, which allow one to establish a link between magnetic photon and p-wave pion absorption.

Abstract
We study the 2p-2h contribution to the deep inelastic inclusive electron scattering by including both the meson exchange currents and the nucleon-nucleon correlations. A satisfactory agreement with the available experimental data is achieved. In the same frame p-wave pion absorption at threshold is also examined; it is shown that a strong quenching is required to account for the π-nucleus absorptive potential deduced from pionic atoms data. Finally the conditions are explored, which allow one to establish a link between magnetic photon and p-wave pion absorption.
