Total and differential cross sections and polarization effects in proton-proton elastic scattering at RHIC
The physics program, the setup, and the performance of an experiment to measure elastic scattering of polarized protons at the Relativistic Heavy Ion Collider (RHIC) are described. In the medium t range, diffractive region, with four momenta transferred 0.006 < t < 1.5 (GeV=c), the experiment will address one of the main, unsolved problems in particle and nuclear physics: long-range QCD and con...
متن کاملPhenomenological 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...
متن کاملSlope 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...
متن کاملParity Violation in Proton-Proton Scattering
Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-proton parity violation experiments are presently either being performed or are being prepared for execution in the near future: at TRIUMF at ...
متن کاملTwo-Pion Exchange in proton-proton Scattering
The cross section and the spin-correlation observable, CNN, measured in the region from 0 to 12 GeV/c Plab at 90 o provide an excellent testing ground for our theories of hadronic interactions. These data have been the focus of a number of experimental [1] and theoretical studies [2]. There is an apparent simplification of the amplitude in the region from 4 GeV/c to 8 GeV/c. At 90 ◦ the spin-co...
