Abstract:

We propose a procedure to extrapolate the nuclear spectral function P(|k|E) obtained from nonrelativistic many-body theory to large values of three-momentum and removal energy. Our approach is based on phenomenological information extracted from both soft hadron-nucleus interactions, in the regime where the proton inclusive spectrum is dictated by Regge asymptotic, and deep-inelastic lepton-nucleus collisions. The extrapolated P(|k|E) is used to compute the semi-inclusive spectra of backward protons produced in electron-nucleus scattering.
