Relativistic Greenʹs function approach to charged-current neutrino–nucleus quasielastic scattering Original Research Article

A relativistic Greenʹs function approach to inclusive quasielastic charged-current neutrino–nucleus scattering is developed. The components of the hadron tensor are written in terms of the single-particle Greenʹs function, which is expanded on the eigenfunctions of the nuclear optical potential, so that final state interactions are accounted for by means of a complex optical potential but without a loss of flux. Results for the (νμ,μ−) reaction on 16O and 12C target nuclei are presented and discussed.
