Polarization-transfer components for He-4(e(-->),e(')p(-->))H-3 and O-16(e(-->),e'p(-->))N-15 are computed within the relativistic multiple-scattering Glauber approximation (RMSGA). The RMSGA framework adopts relativistic single-particle wave functions and electron-nucleon couplings. The predictions closely match those of a relativistic plane-wave model indicating the smallness of the final-state interactions for polarization-transfer components. Also short-range correlations play a modest role for the studied observables, as long as small proton missing momenta are probed in quasielastic kinematics. The predictions with free and various parametrizations for the medium-modified electromagnetic form factors are compared to the world data.
