Phase-Shift Analysis of Proton-Proton Scattering at PL=12GeV/c

Phenomenological analysis connecting proton-proton and antiproton-proton elastic scattering

Based on the behavior of the elastic scattering data, we introduce an almost model-independent parametrization for the imaginary part of the scattering amplitude, with the energy and momentum transfer dependences inferred on empirical basis and selected by rigorous theorems and bounds from axiomatic quantum field theory. The corresponding real part is analytically evaluated by means of dispersi...

Slope Analysis for Elastic Proton-proton and Proton-antiproton Scattering

The diffraction slope parameter is investigated for elastic proton-proton and protonantiproton scattering based on the all available experimental data at intermediate square of momentum transfer in the main. Energy dependence of the elastic diffraction slope is approximated by various analytic functions in a model-independent fashion. The expanded standard logarithmic approximations allow to de...

NONDYNAMICAL ANALYSIS OF SPIN AMPLITUDES IN PION-PROTON ELASTIC SCATTERING IN OPTIMAL FORMALISM AT 6.0 GeV/C

Optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. Invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. Transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 GeVIC

Unique Determination of Three Proton - Proton Scattering Parameters at 9

Duality and Proton - Proton Scattering at All Angles

: \ We obtain a very good description of all available large angle pp elastic scattering data using a dual model with logarithmic trajectories. Our fit strongly suggests that the dual amplitude is responsible for filling in ,a pronounced dip produced by the Pomeranchuk singularity. This new explanation of the shoulder in pp data survives the test of an enormous extrapolation from s N, 26-(GeV/~...
