چکیده

We discuss effects of reflective scattering for hadron and heavy nuclei collisions at the LHC and asymptotical energies. It is shown that the reflective scattering might lead to decreasing matter density with energy beyond the LHC energies. Limiting form of energy dependence of hadron density is obtained. Unitarity upper bound for the absolute value of the real part of elastic scattering amplitude and two-particle inelastic binary reactions amplitudes in impact parameter representation is two times less than the corresponding bound for the imaginary part of the elastic scattering amplitude. The former limit restricts a possible odderon contribution.

Features of elastic scattering at small t at the LHC

The problems linked with the extraction of the basic parameters of the hadron elastic scattering amplitude at the LHC are explored. It is shown that one should take into account the saturation regime which will lead to new effects at the LHC.

Impact-Picture Phenomenology for π±p, K±p and pp, p̄p Elastic Scattering at High Energies

We present an extension to πp and Kp elastic scattering at high energies of the impactpicture phenomenology we first proposed more than twenty years ago, for pp and p̄p elastic scattering. We show, in particular, that the analytic form of the opacity function for the proton obtained previously is compatible with the experimental results on πp and Kp elastic scattering at high energies. It is pro...

Pp Elastic Scattering at Lhc and Signature of Chiral Phase Transition at Large |t|

A model of pp and ¯ pp elastic scattering developed previously to analyze ISR and SPS Collider data is extended to predict pp elastic differential cross section at LHC at c.m. energy of 14 TeV and momentum transfer range |t| = 0-10 GeV 2. Role of the gauged linear σ-model as an underlying field theory model describing nucleon structure and elastic scattering is discussed. Possibility of finding...

Elastic Cross-Section and Luminosity Measurement in ATLAS at LHC

Recently the ATLAS experiment was complemented with a set of ultra-small-angle detectors located in “Roman Pot” inserts at 240m on either side of the interaction point, aiming at the absolute determination of the LHC luminosity by measuring the elastic scattering rate at the Coulomb Nuclear Interference region. Details of the proposed measurement the detector construction and the expected perfo...

TOTEM: The experiment to measure the total proton–proton cross section at LHC

TOTEM is an experiment dedicated to the measurement of the proton–proton total cross section (σ TOT ) at LHC, i.e. the probability that two protons interact at the center of mass energy of 14 TeV. In addition to that, it will also study the proton–proton elastic scattering and diffractive dissociation processes. TOTEM foresees specific measurements and experimental techniques which are very dif...
