Large Rapidity Gaps in proton-nucleus interaction

High Energy Physics - Phenomenology 2023-11-02 v2

Abstract

We analyse the cross-section of events with Large Rapidity Gaps observed in proton-lead collisions by the CMS collaboration. The role of the transverse size of elementary pNpN amplitude is discussed. We emphasize that the cross-section of incoming proton dissociation caused by the photon radiated off the lead ion is close to the value of dσ/dΔηFd\sigma/d\Delta\eta^F measured by the CMS, and it is not clear why there is no room in the data for the Pomeron-induced contribution
