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
Azimuthal Angular Distributions in EDDE as Spin-Parity Analyser and Glueball Filter for LHC
Exclusive Double Diffractive Events (EDDE) are analysed as the source of
information about the central system. Experimental possibilities for exotic
particles searches are considered. From the reggeized tensor current picture
some azimuthal angle dependences were obtained to fit the data from WA102
experiment and to make predictions for LHC collider.Comment: LaTeX, 20 pages, 7 figures, references are adde
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
Towards Extraction of and cross-sections from Charge Exchange Processes at the LHC
We study the possibilities to analyse the data on leading neutrons production
at first LHC runs. These data could be used to extract from it and
cross-sections. In this note we estimate relative contributions of
, and reggeons to charge exchanges and discuss related
problems of measurements.Comment: 8 pages, 9 figures, to be publishe
