The theory describing the hadron-mediated photon-nucleus interaction is generalized with the introduction of large-mass intermediate states. It is shown that if the VDM is valid for the photoproduction of large masses, the hadron-mediated photon-nucleus cross-section is proportional to the hadron-nucleus total cross-section also in the presence of large intermediate masses. The theory is applied to the available experiment of photon-nucleus total cross-section between 20 and 185 GeV, and explains the apparent increase of the transparency of the nucleus with the energy.

Abstract
The theory describing the hadron-mediated photon-nucleus interaction is generalized with the introduction of large-mass intermediate states. It is shown that if the VDM is valid for the photoproduction of large masses, the hadron-mediated photon-nucleus cross-section is proportional to the hadron-nucleus total cross-section also in the presence of large intermediate masses. The theory is applied to the available experiment of photon-nucleus total cross-section between 20 and 185 GeV, and explains the apparent increase of the transparency of the nucleus with the energy.File in questo prodotto:
