High - energy spin effects and structure of elastic scattering amplitude
نویسنده
چکیده
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.

Spin-flip Amplitude of Hadron Elastic Scattering and Possible Polarization Effects at RHIC
With relation to the RHIC spin programwe research the polarization effects in elastic proton-proton scattering at small momentum transfer and in the diffraction dip region. The calculations take into account the Coulomb-hadron interference effects including the additional Coulomb-hadron phase. In particular we show the impact of the form of the hadron potential at large distances on the behavio...

Features of high energy pp and pA elastic scattering at small t Abstract A 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 parts of the spin-non-flip and spin-flip amplit...

The equations for spin evolution of a particle in a storage ring are obtained considering contributions from the tensor electric and magnetic polarizabilities of the particle along with the contributions from spin rotation and birefringence effect in polarized matter of an internal target. Study of the spin rotation and birefringence effects for a particle in a high energy storage ring provides...

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...
متن کاملThe Pp2 Pp Experiment at Rhic *
The PP2PP experiment is devoted to the proton – proton elastic scattering measurements at the Relativistic Heavy Ion Collider (RHIC) at the centre-of-mass energies 50 ≤ √ s ≤ 500 GeV and the four-momentum transfer 0.0004 ≤ |t| ≤ 1.3 GeV. The option of polarized proton beams offers a unique possibility to investigate the spin dependence of the proton elastic scattering in a systematic way. The e...
