Abstract
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.

Aspects of a dynamical gluon mass approach to elastic hadron scattering at LHC

TL;DR: In this paper, the main features of the recent LHC data on elastic scattering can be described by a QCD-inspired formalism with a dynamical infrared mass scale, and new developments on the dynamical gluon mass approach are reported, with emphasis on a method to estimate uncertainty bounds in the predictions for the high energy scattering observables.

Extension of the axiomatic analyticity domain of scattering amplitudes by unitarity-I

TL;DR: In this article, it was shown that the pion-pion scattering amplitude can be continued until the border-line of the double-spectral function, except for the case that the nearest singularities are induced by two-particle unitarity.

Unitarity and High-Energy Behavior of Scattering Amplitudes

TL;DR: In this paper, upper and lower bounds of the imaginary part of a scattering amplitude are obtained for physical and unphysical values of the scattering angle, respectively, from unitarity alone, and it is shown that the total cross section cannot increase faster than the logarithm squared of the energy under assumptions appreciably more general than Mandelstam representation.
