Which Pomeron survives at LHC energies?    [PDF]

A. Lengyel, Z. Tarics

An eikonalized elastic proton-proton and proton-antiproton scattering
amplitude, based on the suggestion of a finite sum of ladder diagrams,
calculated from QCD and the number of $s-$channel gluon rungs and
correspondingly the powers of logarithms in total cross section depends on
available increasing energy. Explicit expressions for total cross section
involving three and four rungs (four and five prongs), as highest terms,
respectively) are fitted to the all available proton-proton and
proton-antiproton total cross section data. Predictions for pp total cross
section at LHC energy are given and compared with prediction of several
Regge-models including possible hard Pomeron contribution.
