The contribution of two-particle–two-hole final states in electron-nucleus scattering

As an introduction to the topic, the detailed calculation of the electron nucleus cross section will be presented. The analysis will be performed within three approximations: the impulse approximation, the plane wave impulse approximation and the relativistic plane wave impulse approximation [Nucl.Phys. A632 (1998) 323-362]. This part of the seminar will be finished with a discussion about two-body current interactions and the factorization issues therein. The second part of the seminar will be devoted to the theoretical framework describing the 2p2h final states contribution in the extended factorization ansatz [Phys.Rev. C92 (2015) 024602].
