Abstract
AbstractWe analyse the cross-section of events with Large Rapidity Gaps observed in proton–lead collisions by the CMS Collaboration (arXiv:2301.07630). The role of the transverse size of elementary pN 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 $$d\sigma /d\Delta \eta ^F$$
