Título: | A study of shadowing in heavy nuclei |
Autor: | Cocho, G.; Gregório, M. A.; León, Juan CSIC ORCID; Rotelli, P. | Fecha de publicación: | 1974 | Editor: | Elsevier | Citación: | Nuclear Physics B 78: 269 (1974) | Resumen: | The theory for shadowing of real and virtual photons in heavy nuclei is presented in the context of the generalized vector-meson dominance (GVMD) model. In particular, the consequence of including off-diagonal elements in GVMD is investigated. It is found that including a positive real/imaginary part in the virtual photon-hadron amplitude considerably improves agreement with experiments. Such an important real part is consistent with the energy dependence of the vector-meson electroproduction data. These data also exhibit a feature which may be called the decoupling of the pomeron as a function of q*, the photon mass. The relation to a similar feature of the pure hadronic interactions is discussed. | URI: | http://hdl.handle.net/10261/81985 | DOI: | 10.1016/0550-3213(74)90283-1 | Identificadores: | doi: 10.1016/0550-3213(74)90283-1 issn: 0550-3213 |
