“…(A.1.4), we can now calculate ds dt , the elastic differential cross section as a function of |t|, for various values of √ s. The calculated differential cross section at the Tevatron ( √ s = 1800 GeV) is shown in Fig. 5 and compared with the experimental data from E710 [13].…”

We show that the data on γp and γγ interactions can be derived from the pp andpp forward scattering amplitudes using vector meson dominance and the additive quark model. The nucleon-nucleon data are parameterized using a model where high energy cross sections rise with energy as a consequence of the increasing numbers of soft partons populating the colliding particles. We present detailed descriptions of the data on the total and elastic cross sections, the ratio of the real to imaginary part of the forward scattering amplitude, and on the slope of the differential cross sections for pp,pp, γp, γγ, γp → γV and γγ → V i V j reactions, where V = ρ, ω, φ. We make a wide range of predictions for future HERA and LHC experiments and for γγ measurements at LEP. *

“…At the SppS, for √ s = 546 GeV, a change of slope at |t| ≈ 0.14 GeV 2 has been observed, while the inclusion of a quadratic term in the exponent did not improve the fit significantly [5]. At the Tevatron [6,7,8,9] no deviations from pure exponential functions were observed, except at larger |t| where the influence of the shoulder (∼ 0.8 GeV 2 at √ s = 0.546 TeV and ∼ 0.6 GeV 2 at 1.8 and 1.96 TeV) becomes visible. At the LHC, at 7 TeV as well as at 8 TeV, all data published so far [10,11,12,13] have been compatible with a pure exponential shape.…”

The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy √ s = 8 TeV based on a high-statistics data sample obtained with the β * = 90 m optics. Both the statistical and systematic uncertainties remain below 1 %, except for the t-independent contribution from the overall normalisation. This unprecedented precision allows to exclude a purely exponential differential cross-section in the range of fourmomentum transfer squared 0.027 < |t| < 0.2 GeV 2 with a significance greater than 7 σ. Two extended parametrisations, with quadratic and cubic polynomials in the exponent, are shown to be well compatible with the data. Using them for the differential cross-section extrapolation to t = 0, and further applying the optical theorem, yields total cross-section estimates of (101.5 ± 2.1) mb and (101.9 ± 2.1) mb, respectively, in agreement with previous TOTEM measurements.This article is dedicated to the memory of Prof. E. Lippmaa and Prof. M. Lo Vetere who passed away recently

“…The first set consists of all the available data in the range, 546 GeV ≤ √ s ≤ 13 TeV. We take into account the data measured at √ s = 546 GeV by the UA4 [8,9] and CDF [10] collaborations, at √ s = 1.8 TeV by the E710 [11][12][13] and CDF [10] collaborations and at √ s = 2.76 TeV [2],…”

“…The centre of mass energy spans from fixed target experiments at √ s ∼ 10 GeV to the LHC energies of √ s ∼ 10 TeV. Focusing on the TeV scale, except the TOTEM, there are earlier data at √ s = 546 GeV measured by the UA4 collaboration [8,9] and the CDF collaboration [10], and at √ s = 1.8 TeV measured by the E710 collaboration [11][12][13] and the CDF collaboration [10]. These measurements have accumulated a rich set of data, upon which various theoretical and phenomenological models have been developed [14][15][16][17][18].…”

The cross sections of the high energy proton-proton scattering are studied in a holographic QCD model, focusing on the Regge regime. In our model setup, the involved nonperturbative partonic dynamics is described by the Pomeron exchange, which is realized by applying the Reggeized spin-2 particle propagator together with the proton gravitational form factor obtained from the bottom-up AdS/QCD model. Our model includes three adjustable parameters which are to be fitted by experimental data. We show that both the resulting differential and total cross sections are consistent with data, including the ones recently measured at √ s = 13 TeV by the TOTEM collaboration at the LHC. Our results imply that the present framework works well in the considered TeV scale, and further applications to other high energy scattering processes, in which the involved strong interaction can be approximated by the Pomeron exchange, are possible.
