The exclusive Z0 photoproduction at high energies in γp(A), pp
and AA collisions is investigate within the color dipole formalism. We
generalize the description of the deeply virtual compton scattering (DVCS)
process, which describe quite well the HERA data, for the production of Z0
bosons and estimate the total cross section for the exclusive process γ∗h→Z0h (h=p,A) for different energies, photon virtualities and atomic
numbers. As hadrons at collider energies are a source of Weizs\"{a}cker -
Williams photons, we consider electromagnetic interactions in hadron-hadron
collisions at Tevatron and LHC energies and estimate the rapidity distribution
and total cross section for Z0 production in the hh→hZ0h process.
This is the first estimation for such a process in literature. It can allow us
to study, for instance, the physics of hadronic Z0 decays in a clean
environment characterized by two rapidity gaps. Our results indicate that the
experimental analyzes of this process could be feasible in pp but the physics
scenario for AA collisions is not promising.Comment: 6 pages, 2 figures, 1 table; The erroneus additional factor of 2Ï€
