Determination of the structure of the high energy hadron elastic scattering amplitude at small angles
A new method for the determination of the real part of the elastic scattering amplitude is examined for high energy proton-proton and proton-nuclei elastic scattering at small momentum transfer. This method allows us to decrease the number of model assumptions, to obtain the real part in a narrow region of momentum transfer and to test different models for hadron-nuclei scattering. ∗Unité de Re...
متن کاملHigh - energy spin effects and structure of elastic scattering amplitude
A behavior of imaginary and real parts of the high-energy elastic hadron scattering amplitude is examined in the diffraction region. It is shown that the interference between Coulomb and hadronic scattering at small momentum transfers and especially in the region of diffractive minimum can bring some information about the structure of the hadron spin-non-flip amplitude.
متن کاملOn the relation between the Deuteron Form Factor at High Momentum Transfer and the High Energy Neutron-Proton Scattering Amplitude
We use non-relativistic dynamics to relate the deuteron form factor at high momentum transfer to the high energy neutron-proton scattering amplitude. This relation implies that an accurate computation of the form factors at large Q2 requires a simultaneous description of the lowest phase-shifts of the nucleon-nucleon elastic scattering at laboratory kinetic energy T ∼ Q/2mN . Computing these ph...
متن کاملAnalyticity of the Scattering Amplitude, Causality and High-Energy Bounds in Quantum Field Theory on Noncommutative Space-Time
In the framework of quantum field theory (QFT) on noncommutative (NC) space-time with the symmetry groupO(1, 1)×SO(2), we prove that the Jost-Lehmann-Dyson representation, based on the causality condition taken in connection with this symmetry, leads to the mere impossibility of drawing any conclusion on the analyticity of the 2 → 2scattering amplitude in cosΘ, Θ being the scattering angle. Dis...
متن کاملElastic Electron - Deuteron Scattering at High Energy
Relativistic formulae for the deuteron electromagnetic form factors are calculated in the impulse approximation retaining terms to all orders in Q2/M2 z wc>2. The formulae are given as double integrals over the deuteron wave functions in momentum space, and hence can be evaluated for any deuteron model. We evaluate these formulae numerically for 9 different deuteron models: Reid soft core, two ...
