Photon-photon and pomeron-pomeron processes in peripheral heavy ion collisions
(2000-06-01)
We estimate the cross sections for the production of resonances, pion pairs, and a central cluster of hadrons in peripheral heavy-ion collisions through two-photon and double-pomeron exchange, at energies that will be ...
RELATING THE QCD POMERON TO AN EFFECTIVE GLUON MASS
(American Physical Soc, 1993-01-01)
We construct the Pomeron as an exchange of two nonperturbative gluons, where the nonperturbative gluon propagator is described by an approximate solution of the Schwinger-Dyson equation which contains a dynamically generated ...
Compatibility of a model for the QCD-Pomeron and chiral-symmetry breaking phenomenologies
(1997-01-02)
The phenomenology of a QCD-Pomeron model based on the exchange of a pair of non-perturbative gluons, i.e. gluon fields with a finite correlation length in the vacuum, is studied in comparison with the phenomenology of QCD ...
Are two gluons the QCD pomeron?
(1999-03-01)
Collider experiments have recently measured the production cross section of hard jets separated by a rapidity gap as a function of transverse momentum and gap size. We show that these measurements reveal the relative ...

(1998-12-01)
Collider experiments have recently measured the production cross section of hard jets separated by a rapidity gap as a function of transverse momentum and gap size. We show that these measurements reveal the relative ...
RESONANCE PRODUCTION IN PERIPHERAL HEAVY-ION COLLISIONS
(World Scientific Publ Co Pte Ltd, 1994-07-20)
Heavy-ion collisions at ultrarelativistic energies may be used as a powerful source of photons and pomerons. We compute the rates for pseudoscalar meson production through two-photon and two-pomeron scattering, at energies ...
Hadronic physics in peripheral heavy Ion collisions
(Sociedade Brasileira de Física, 2002-12-01)
We discuss the production of hadronic resonances in very peripheral heavy ion collisions, where the ions collide with impact parameter larger than twice the nuclear radius and remain intact after the collision. We compare ...
DIFFRACTION AND THE GLUON MASS
(American Physical Soc, 1993-09-01)
We recently proposed a QCD Pomeron described by the exchange of two nonperturbative gluons characterized by a dynamically generated gluon mass. It is shown here that data on elastic scattering, exclusive rho production in ...
Elastic scattering and the proton form factor
(World Scientific Publ Co Pte Ltd, 2006-12-28)
We use the QCD pomeron model proposed by Landshoff and Nachtmann to compute the differential and the total cross-sections for pp scattering in order to discuss a QCD-based approach to the proton form factor. This model is ...
Glueballs in peripheral heavy-ion collisions
(1995-12-01)
We estimate the cross-section for glueball production in peripheral heavy-ion collisions through two-photon and double-Pomeron exchange, at energies that will be available at RHIC and LHC. Glueballs will be produced at ...
