Two-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...
متن کاملTwo-photon Exchange in Electron-proton Elastic Scattering: Theory Update
Recent theoretical developments in the studies of two-photon exchange effects in elastic electron-proton scattering are reviewed. Two-photon exchange mechanism is considered a likely source of discrepancy between polarized and unpolarized experimental measurements of the proton electric form factor at momentum transfers of several GeV. This mechanism predicts measurable effects that are current...
متن کاملThe Two-Boson-Exchange Correction to Parity-Violating Elastic Electron-Proton Scattering
We calculate the two-boson-exchange (TBE) corrections to the parity-violating asymmetry of the elastic electron-proton scattering in a simple hadronic model including the nucleon and the ∆(1232) intermediate states. We find that ∆ contribution δ∆ is, in general, comparable with the nucleon contribution δN and the current experimental measurements of strange-quark effects in the proton neutral w...
متن کاملChiral two - pion exchange and proton - proton partial - wave analysis
The chiral two-pion exchange component of the long-range pp interaction is studied in an energy-dependent partial-wave analysis. We demonstrate its presence and importance, and determine the chiral parameters ci (i = 1, 3, 4). The values agree well with those obtained from pion-nucleon amplitudes. 11.80.Et, 12.39.Fe, 13.75.Cs, 21.30.-x Typeset using REVTEX
متن کاملNONDYNAMICAL 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
