Inelastic diffraction and color-singlet gluon-clusters in high-energy hadron-hadron and lepton-hadron collisions

摘要

It is proposed, that ``the colorless objects'' which manifest themselves inlarge-rapidity-gap events are color-singlet gluon-clusters due toself-organized criticality (SOC), and that optical-geometrical concepts andmethods are useful in examing the space-time properties of such objects. Asimple analytical expression for the $t$-dependence of the inelastic singlediffractive cross section $d\sigma/dt$ ($t$ is the four-momentum transfersquared) is derived. Comparison with the existing data and predictions forfuture experiments are presented. The main differences and similarities betweenthe SOC-approach and the ``Partons in the Pomeron (Pomeron andReggeon)''-approach are discussed.
