    "abstract": "The nuclear response to longitudinally polarized electrons, detected in\ncoincidence with out-of-plane high-energy protons, is discussed in a simple\nmodel where the ejectile wave function is approximated as a plane wave with a\ncomplex wave vector. This choice is equivalent to solve the problem of\nFinal-State Interactions (FSI) in homogeneous nuclear matter, as the residual\nnucleus can be described to a first approximation when dealing with very fast\nemitted protons. The main advantage of the present method is that in the\nframework of the Distorted-Wave Impulse Approximation (DWIA) it allows for an\nanalytical derivation of all the components of the nuclear response. It emerges\nthat cancellations among the leading contributions determine the very small\nabsolute size of the socalled fifth structure function and produce a nontrivial\nasymptotic scaling of the related helicity asymmetry for large values of the\nmomentum transfer.",
