  "abstract": "The splitting between the charge-longitudinal and spin-transverse responses is explained in a model whose inputs are the effective interactions in the particle-hole channels in the frame of the first order boson loop expansion. It is shown that the interplay between $\\omega$-meson exchange and box diagrams (two-meson exchange with simultaneous excitation of one or two nucleons to $\\Delta$'s) mainly rules the longitudinal response, while in the transverse one the direct $\\Delta$ excitations almost cancel the one-loop correction and the response is mainly governed by the $\\rho$-meson rescattering inside the nucleus. It is also shown that a small variation in the nuclear densities may explain the observed discrepancies between different nuclei.",
