HELICITY AND PLANAR AMPLITUDES IN PION-PROTON SCATTERING AT 6.0 GeV/c
Authors: not saved
Abstract:
In addition to optimal conditions, invariant laws of Lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 GeV/c. By normalizing the differential cross-section to unity, the magnitudes of helicity amplitudes and the angle between them are determined. Planar amplitudes are found in terms of the helicity amplitudes and the angle between momentum vector and quantization direction in the reaction plane.

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

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...

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...

We revisit the recently proposed method for the determination of the ππ scattering length combination a0 − a2, based on the study of the π0π0 spectrum in K+ → π+π0π0 . In view of a precision measurement, we discuss here the effects due to smaller absorptive contributions to the K+ → π+π0π0 and K+ → π+π+π− amplitudes. We outline a method of analysis that can lead to a precision determination of ...
