Spin dependent elastic antiproton interactions

چکیده
Relativistic formulae for spin averaged and spin dependent one photon exchange differential cross sections are developed for spin half fermion fermion elastic scattering. Spin transfer cross sections are important for the Polarized Antiproton eXperiments (PAX) project at GSI Darmstadt. In particular, cross sections for polarization transfer in antiproton electron p̄ e↑ −→ p̄ ↑ e and antiproton proton p̄ p↑ −→ p̄↑ p elastic collisions are presented.

Antiproton polarization induced by lepton interactions
We present expressions for electromagnetic helicity amplitudes and spin observables for any elastic spin 1/2 spin 1/2 scattering to first order in QED. In particular all electromagnetic helicity amplitudes and spin observables for elastic antiproton-electron and antiproton-proton scattering via single t-channel photon exchange are presented. Spin observables are required to describe the rate of...
متن کاملSpin Matrix Elements for the Elastic Proton-proton and Proton-antiproton Collisions
Abstract Motivated by the present extensive RHIC (BNL) spin program and further PAX project at FAIR, we study the possibility of explicit reconstruction of full set of helicity amplitudes by joint consideration of elastic proton-proton and proton-antiproton scattering. Procedure is based on the derivative relations for the helicity amplitudes, explicit parametrization of the leading spin non-fl...
متن کاملElastic 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...
متن کاملThe Explicit Procedures for Reconstruction of Full Set of Helicity Amplitudes in Elastic Proton-Proton and Proton-Antiproton Collisions
Abstract. The explicit procedures are described for reconstruction of the full set of helicity amplitudes in proton-proton and proton-antiproton elastic scattering. The procedures are based on the derivative relations for the helicity amplitudes in s-channel, on the explicit parametrization of the leading spin non flip amplitudes and crossing symmetry relations. Asymptotic theorems are used for...
متن کاملMeasurement of the Spin–Dependence of the p̄p Interaction at the AD–Ring
We propose to use an internal polarized hydrogen storage cell gas target in the AD ring to determine for the first time the two total spin–dependent p̄p cross sections σ1 and σ2 at antiproton beam energies in the range from 50 to 450 MeV. The data obtained are of interest by themselves for the general theory of p̄p interactions since they will provide a first experimental constraint of the spin–s...
