Constraints on color dipole-nucleon cross section from diffractive heavy quarkonium production
We study the hard color dipole-nucleon cross section within perturbative QCD and discuss its relation to observables in diffractive leptoproduction of heavy quarkonium. The dipole cross section calculated with the unintegrated gluon density of the nucleon substantially differs from the well-known perturbative form σdip ∼ b 2 for b > 0.3fm, where b is the transverse separation of the dipole. We ...
متن کاملFactorial moment analyses in diffractive lepton-nucleon scattering
It is pointed out that ”the colorless objects” in diffractive lepton-nucleon scattering in the small-xB region can be probed by measuring the scaled factorial moments of final-state-hadrons and the dependence of their scaling behavior upon the diffractive kinematic variables. The Monte Carlo implementation of RAPGAP and JETSET are discussed as illustrative examples. The results of these model-c...
متن کاملDiffractive Dis from the Color Dipole Bfkl Pomeron
The microscopic QCD mechanism of diffractive DIS (DDIS) is a grazing, quasielastic scattering of multiparton Fock states of the photon on the target proton, which is best described viewing these Fock states as systems of color dipoles spanned between quarks, antiquarks and gluons [1, 2, 3]. In inclusive DIS, the effect of gluons in the photon is reabsorbed into the Bjorken x dependence of the c...
متن کاملFormation of color-singlet gluon-clusters and inelastic diffractive scattering
This is the extensive follow-up report of a recent Letter in which the existence of self-organized criticality (SOC) in systems of interacting soft gluons is proposed, and its consequences for inelastic diffractive scattering processes are discussed. It is pointed out, that color-singlet gluon-clusters can be formed in hadrons as a consequence of SOC in systems of interacting soft gluons, and t...
متن کاملFormation of color-singlet gluon-clusters and inelastic diffractive scattering
It is proposed, that color-singlet gluon-clusters can be formed in hadrons as a consequence of self-organized criticality (SOC) in systems of interacting soft gluons, and that the properties of such spatiotemporal complexities can be probed experimentally by examing inelastic diffractive scattering. Theoretical arguments and experimental evidences supporting the proposed picture are presented —...
