“…12 the 14 TeV plot is extended to very large |t| pointing out the possible smooth connection with the supposedly universal tail at 27.4 GeV [36]. We recall the situation with similar plot drawn in the 7 TeV case [3], where the measurements reached larger |t| ≈ 2.5 GeV 2 and the conjecture of the universality of the tail at such high energy encounters motivation.…”

Using a unified analytic representation for the elastic scattering amplitudes of pp scattering valid for all energies above 20 GeV, the behavior of observables in the LHC collisions in the range √ s = 2.76-14 TeV is discussed. After the precise description of dσ/dt at 7 TeV, we discuss the energy dependence of the amplitudes and expect that the proposed analytical forms give equally good predictions for the future experiments.

Model-independent data reductions of elastic proton–proton scattering

Abstract. New developments in empirical analyses of the proton-proton differential cross section data at high energies are reported. Making use of an unconstrained model-independent parametrization for the scattering amplitude and two different fit procedures, all the experimental data in the center-of-mass energy interval 19.4 -62.5 GeV are quite well described (optical point and data above the region of Coulombnuclear interference). The contributions from the real and imaginary parts of the amplitude beyond the forward direction are discussed and compared with the results from previous analyses and phenomenological models. Extracted overlap functions (impact parameter space) are outlined and a critical discussion on model-independent analyses and results are also presented.PACS. 13.85.Dz Elastic scattering -13.85.-t Hadron-induced high-energy interactions

“…As already discussed in some detail [6,9,12] this condition limits the analysis to six sets of pp elastic scattering data, at √ s = 19.4 GeV (from the Fermilab and CERN SPS) and √ s = 23.5, 30.7, 44.7, 52.8 and 62.5 GeV (from the CERN ISR). In addition, we make use of the empirical result that at the ISR energy region (23.5 -62.5 GeV) the differential cross section data above q 2 ∼ 4 GeV 2 do not depend on the energy [55][56][57][58]. This fact allows the inclusion in each set (ISR) the data at 27.4 GeV (from Fermilab), covering the large momentum transfer region: 5.5 ≤ q 2 ≤ 14.2 GeV 2 (see [9] for a quantitative discussion on this respect).…”

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.
