“…0.09−1.0 GeV 2 for pp andp p, the slope was found to be smaller, 10.34 ± 0.19 ± 0.06 GeV −2 and 10.68 ± 0.20 ± 0.06 GeV −2 , respectively, in agreement with [111]. Results for the slope in the smaller interval were in agreement not only with [111] but also with [124] whose measurement covers the interval |t| = 1.0 × 10 −3 to 31 × 10 −3 GeV 2 . The larger |t| interval is not discussed in [124].…”

This review describes the development of the physics of hadronic cross sections up to recent LHC results and cosmic ray experiments. We present here a comprehensive review -written with a historical perspective -about total cross sections from medium to the highest energies explored experimentally and studied through a variety of methods and theoretical models for over 60 years. We begin by recalling the analytic properties of the elastic amplitude and the theorems about the asymptotic behavior of the total cross section. A discussion of how proton-proton cross sections are extracted from cosmic rays at higher than accelerator energies and help the study of these asymptotic limits, is presented. This is followed by a description of the advent of particle colliders, through which high energies and unmatched experimental precisions have been attained. Thus the measured hadronic elastic and total cross sections have become crucial instruments to probe the so called soft part of QCD physics, where quarks and gluons are confined, and have led to test and refine Regge behavior and a number of diffractive models. As the c.m. energy increases, the total cross section also probes the transition into hard scattering describable with perturbative QCD, the so-called mini-jet region. Further tests are provided by cross section measurements of γ p, γ * p and γ * γ * for models based on vector meson dominance, scaling limits of virtual photons at high Q 2 and the BFKL formalism. Models interpolating from virtual to real photons are also tested.

“…In the analyses of past experiments -see e.g. [1][2][3][4][5][6][7][8] (ISR), [9,10] (SppS), [11] (Tevatron) -a simplified interference formula was used. This so-called Simplified West-Yennie (SWY) formula [12] is based on restrictive assumptions on the hadronic amplitude, implying in particular a purely exponential modulus and a constant phase for all t (see the discussion in Section 6.1.4).…”

Measurement of elastic pp scattering at $$\sqrt{\hbox {s}} = \hbox {8}$$ s = 8 TeV in the Coulomb–nuclear interference region: determination of the $$\mathbf {\rho }$$ ρ -parameter and the total cross-section

et al. 2016

The TOTEM experiment at the CERN LHC has measured elastic proton-proton scattering at the centre-ofmass energy √ s = 8 TeV and four-momentum transfers squared, |t|, from 6 × 10 −4 GeV 2 to 0.2 GeV 2 . Near the lower end of the t-interval the differential cross-section is sensitive to the interference between the hadronic and the electromagnetic scattering amplitudes. This article presents the elastic cross-section measurement and the constraints it arXiv:1610.00603v1 [nucl-ex] 3 Oct 2016 2 imposes on the functional forms of the modulus and phase of the hadronic elastic amplitude. The data exclude the traditional Simplified West and Yennie interference formula that requires a constant phase and a purely exponential modulus of the hadronic amplitude. For parametrisations of the hadronic modulus with second-or third-order polynomials in the exponent, the data are compatible with hadronic phase functions giving either central or peripheral behaviour in the impact parameter picture of elastic scattering. In both cases, the ρ-parameter is found to be 0.12 ± 0.03. The results for the total hadronic cross-section are σ tot = (102.9 ± 2.3) mb and (103.0 ± 2.3) mb for central and peripheral phase formulations, respectively. Both are consistent with previous TOTEM measurements.
