With use of a new C + N amplitude which correctly accounts for CNI to all orders in α the values of the parameters ρ^pp , σ _ 1pttot 1pt^pp and B^pp are analysed on the basis of data published by the TOTEM and ATLAS collaborations at energy √(s) = 13 TeV . The result of both joint and separate analyses of these data confirmed, in particular, a noticeable difference between the central values of σ _tot^pp , as measured by the TOTEM and by the ATLAS-ALFA, reaching up to 8 standard deviations in ATLAS experiment.

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.

We show that extraction of the quantities ρ(s)=[T_N(s,0)]/[T_N(s,0)] and σ_(s) from the data on the pp differential cross-section at √(s) = 13 TeV obtained by the TOTEM Collaboration gives results essentially different from those presented in publication if to use a modified formula for Coulomb-nuclear interference. The physical interpretation of these data changes accordingly.

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).

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.

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.

This report presents results of the indirect multivariate "measurements" of model parameters in a task of experimental data description by analytical models with "moderate" nonlinearity. In our "measurements" we follow the recommendations of the GUM-S1 and GUM-52 documents in places where they are appropriate.

Revised August 2013 by S.Roesler and M.Silari（CERN）.35.1.Definitions[1,2]It would be desirable if legal protection limits could be expressed in directly measurable physical quantities.However,this does not allow to quantify biological effects of the exposure of the human body to ionizing radiation.For this reason,protection limits are expressed in terms of so-called protection quantities which,although calculable,are not measurable.Protection quantities quantify the extent of exposure of the human body to ionizing radiation from both whole and partial body external irradiation and from intakes of radionuclides.In order to demonstrate compliance with dose limits,so-called operational quantities are typically used which aim at providing

Revised September 2013 by K.A.Olive（University of Minnesota）and J.A.Peacock（University of Edinburgh）.22.1.Introduction to Standard Big-Bang Model The observed expansion of the Universe[1-3]is a natural（almost inevitable）result of any homogeneous and isotropic cosmological model based on general relativity.However,by itself,the Hubble expansion does not provide sufficient evidence for what we generally refer to as the Big-Bang model of cosmology.While general relativity is in principle capable of describing the cosmology of any given distribution of matter,it is extremely fortunate that our Universe appears to be homogeneous and isotropic on large scales.Together,homogeneity and isotropy allow us to extend the Copernican Principle to the Cosmological Principle,stating that all spatial positions in the

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 Japers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particles, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that are new or heavily revised including those on: Dark Energy, Higgs Boson Physics, Electroweak Model, Neutrino Cross Section Measurements, Monte Carlo Neutrino Generators, Top Quark, Dark Matter, Dynamical Electroweak Symmetry Breaking, Accelerator Physics of Colliders, High-Energy Collider Parameters, Big Bang Nucleosynthesis, Astrophysical Constants and Cosmological Parameters.
