Can the "standard" unitarized Regge models describe the TOTEM data?

Abstract

The standard Regge poles are considered as inputs for two unitarization methods: eikonal and U-matrix. It is shown that only models with three input pomerons and two input odderons can describe the high energy data on pppp and pˉp\bar pp elastic scattering including the new data from Tevatron and LHC. However, it seems that the both considered models (eikonal and U-matrix) require a further modification (e.g., to explore nonlinear reggeon trajectories and/or nonexponential vertex functions) for a more satisfactory description of the data at 19.0 GeVs\leq \sqrt{s}\leq 7 TeV and 0.01 t\leq |t|\leq 14.2 GeV2^{2}.
