Description

(OFFLINE)
Recent results of proton-Pb collisions with large forward rapidity gap events at the LHC show a dominant role of photon exchange over pomeron one.
A comparison of LHC proton-proton, proton-nuclear forward rapidity gap events provides an opportunity for the estimation of
A- and Z- dependencies of pomeron- and photon- exchange contributions, respectively.
