From the exclusive photoproduction of heavy quarkonia at HERA to the EDDE at TeVatron and LHC
Exclusive photoproduction of heavy quarkonia at HERA is analyzed in the
framework of the Regge-eikonal approach together with the nonrelativistic bound
state formalism. Total and differential cross-sections for the process
are calculated. The model predicts
cross-sections of Exclusive Double Diffractive Events (EDDE) at TeVatron and
LHC.Comment: 14 pages, 6 figures, reference is adde
Patterns of the Exclusive Double Diffraction
We consider Exclusive Double Diffractive Events (EDDE) as a powerfull tool to
study the picture of the interaction. Calculations of the cross-sections
for the process are presented in the convenient form for further
experimental applications. We propose measurements of t-distributions in the
joint CMS-TOTEM experiment. It is shown that important information on the
interaction region could be extracted from the diffractive pattern.Comment: 12 pages, 7 figures, to be publishe
