    "abstract": "A model based on the hadronic fluctuations of the real photon is developed to\ndescribe the total photonucleon and photonuclear cross sections in the energy\nregion above the nucleon resonances. The hadronic spectral function of the\nphoton is derived including the finite width of vector-meson resonances and the\nquark-antiquark continuum. The shadowing effect is evaluated considering the\neffective interaction of the hadronic component with the bound nucleons within\na Glauber-Gribov multiple scattering theory. The low energy onset of the\nshadowing effect is interpreted as a possible signature of a modification of\nthe hadronic spectral function in the nuclear medium. A decrease of the\n$\\rho$-meson mass in nuclei is suggested for a better explanation of the\nexperimental data.",
