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

نویسنده

چکیده

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 evidence of a chiral phase transition at large |t| in the proposed TOTEM project at LHC is pointed out.

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...

Elastic pp and p̄p scattering in the models of unitarized pomeron

Elastic scattering amplitudes with pomeron singularity by construction meeting the main unitarity bounds valid at high energy are considered. Restrictions for a form of pomeron singularity are stressed. The models of double and triple (at t = 0) pomeron pole with additional terms important for low energies are compared with all existing experimental data on pp and p̄p total and differential cros...

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...

Elastic Proton-proton and Proton-antiproton Scattering: Analysis of Complete Set of Helicity Amplitudes

The differential cross-sections are calculated for proton-proton and proton-antiproton elastic scattering using the phenomenological model based on the analytic parameterizations for global scattering parameters (total cross-section and ρ parameter), crossing symmetry and derivative relations. We confront our model predictions with experimental data in wide range of energy and momentum transfer...

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.
