Abstract

The results on elastic proton–proton scattering that were obtained by the TOTEM Collaboration at the LHC (Large Hadron Collider) energy of 13 TeV are analyzed. It is shown that the statistical significance of these results is questionable in some respects. Specific examples show that the parameter $$\rho$$ extracted from experimental data is model-dependent.

Abstract

The results of a combined description of data on the differential and total scattering cross sections and the $$\rho$$ -parameter for $$p(\bar{p})p$$ collisions in tuning the parameters of an analytic model constructed in order to describe data over a broad region of kinematical variables for $$\sqrt{s}\gtrsim 7$$ GeV and all currently available experimental data on $$t$$ are presented. The experimental data were taken from the COMPAS group (IHEP) compilations and the CLM compilations and were supplemented with data from the FNAL-COLLIDER-D0 and CERN-LHC-TOTEM experiments and with cosmic-ray data from the Pierre Auger Observatory (PAO).

Abstract

The results of a quantitative, statistically complete, description of the total-cross-section data obtained worldwide for hadron–hadron (photon–hadron) collisions and compiled in the Particle Data Group surveys are presented for several versions of a universal analytic parametrization of amplitudes for forward hadron–hadron (photon-hadron) scattering.

Abstract

The experience of using the dynamic atlas of the experimental data and mathematical models of their description in the problems of adjusting parametric models of observable values depending on kinematic variables is presented. The functional possibilities of an image of a large number of experimental data and the models describing them are shown by examples of data and models of observable values determined by the amplitudes of elastic scattering of hadrons. The Internet implementation of an interactive tool DaMoScope and its interface with the experimental data and codes of adjusted parametric models with the parameters of the best description of data are schematically shown. The DaMoScope codes are freely available.

Abstract

For more efficient knowledge exploration and searching for relevant information on the Internet, it is worthwhile to take the level of expertise of the authors of papers and materials into account and assess the reliability of sources. A measure is proposed to assess the level of expertise of authors, which takes the occurrence of relevant ideas and phrases in a text into account. The proposed measure also considers the independence of authors that refer to a particular paper and the chronological characteristics of published works.

Abstract

We present predictions on the total cross sections and on the ratio of the real part to the imaginary part of the elastic amplitude (rho parameter) for present and future pp and pbar p colliders, and on total cross sections for gamma p -> hadrons at cosmic-ray energies and for gamma gamma-> hadrons up to sqrt{s}=1 TeV. These predictions are based on an extensive study of possible analytic parametrisations invoking the biggest hadronic dataset available at t=0. The uncertainties on total cross sections, including the systematic errors due to contradictory data points from FNAL, can reach 1.9% at RHIC, 3.1% at the Tevatron, and 4.8% at the LHC, whereas those on the rho parameter are respectively 5.4%, 5.2%, and 5.4%., 11 pages, 2 figures, 4 tables, RevTeX4
