The photonuclear reaction in the multi-GeV region occurs because of the electromagnetic and hadronic interaction. The later originates due to the hadronic fluctuation, i.e., vector meson, of the photon. The total cross section of the…

Although at small Bjorken x gluons originated from different nucleons in a nucleus overlap in the longitudinal direction, most of them are still well separated in the transverse plane, therefore cannot fuse. For this reason the gluon…
