High energy photoproduction off nuclear targets is studied within the Glauber-Gribov approximation. The photon is assumed to interact as a $q\bar{q}$-system according to the Generalized Vector Dominance Model and as a ``bare photon'' in…
We propose a particle production mechanism analogous to the particle photoproduction processes, arising from the gluon-nucleon interactions in relativistic heavy ion collisions. The comparison is made on the effect of the gluon-nucleon…

It has been known for a long time that the cross section for bottom-quark $b$ production at hadron collider energies exceeds theoretical expectations. An additional contribution from pair-production of light gluinos $\tilde{g}$, of mass 12…
