“…The Collider experiments on elastic pp-scattering brought us closer to answering the question where is asymptopia? In the elastic hadron-hadron scattering the fine structure parameters of diffraction cone such as the slope (1) and curvature (2) considered as a sensitive indicator of the transition to asymptopia [5].…”

“…To look for non-exponential behavior similar to that observed in the ISR [10,11] and LHC [1,2] we have separate those experimental data for pp-scattering which contains large number of experimental points, namely: at E cm = 19.4 [10]; 23.5; 30.7; 44.7; 52.8; 62.5 GeV [11]; 8 [1] and 13 TeV [2].…”

“…Concerning the search for "asymptopia" many years ago Jorge Dias de Deus and Antonio Braz de Padua [1] rightly argued: "At the moment, the situation is such that we do not find any evidence for new and not old-fashioned physics in hadronic diffraction at high energies. Odderon and threshold effects may be there, but do not seem to be relevant for the description of the bulk of the interactions: total cross-section, ratio ρ, differential cross-section, etc".…”

The values of the slope B(s,t) and curvature parameter C(s,t) have been calculated within the framework of the maximal Pomeron and Odderon approach in the wide s- and low t-range with the allowance made for the diffraction cone shape. The absolute values of the averaged curvature parameter <C(s,t)> is predicted to be decreasing depending on s and change of sign at asymptotically large energies far from achievable ones.

“…Although under limited formal condition of validity, this proposal can be assumed as a representation for the Martin's formula applicable, in principle, to all values of s and q 2 . In fact, despite its "hybrid" character the efficacy of this representation in the phenomenological context has been demonstrated, subsequently, by several authors, for both pp and pp scattering and different regions of the momentum transfer and energy with experimental data available [44][45][46][47][48][49][50][51][52][53].…”

Using a novel representation for the Martin's real-part formula without the full scaling property, an almost model-independent description of the proton-proton differential cross section data at high energies (19.4 GeV -62.5 GeV) is obtained. In the impact parameter and eikonal frameworks, the extracted inelastic overlap function presents a peripheral effect (tail) above 2 fm and the extracted opacity function is characterized by a zero (change of sign) in the momentum transfer space, confirming results from previous model-independent analyses. Analytical parametrization for these empirical results are introduced and discussed. The importance of investigations on the inverse problems in high-energy elastic hadron scattering is stressed and the relevance of the proposed representation is commented. A short critical review on the use of Martin's formula is also presented.

“…Introduction. Soft hadronic collisions at high energy are described successfully using Regge and Pomeron phenomenology [1,2]. Yet an outstanding problem is the more basic understanding of pomeron exchange in terms of the underlying quark-gluon-dynamics.…”

We investigate the role of nonperturbative quark-gluon dynamics in soft high energy processes. In order to reproduce differential and total cross sections for elastic protonproton and proton-antiproton-scattering at high energy and small momentum transfer it turns out that we need two scales, the gluonic correlation length and a confinement scale. We find a small gluonic correlation length, a ≃ 0.2 fm, in accordance with recent lattice QCD results.
