Calculation of Spin Observables for Proton-Proton Elastic Scattering in the Bethe-Salpeter Equation

Abstract

Bethe-Salpeter equation is applied to $p$-$p$ elastic scattering. The observables of spin are calculated in the framework of the M matrix using the two-body interaction potential. The parameter of the pseudovector coupling constant is adjusted so as to reproduce the spin singlet part. It is shown that the spin rotation $R(\theta )$ and $A(\theta )$ are improved by the resonance effect for ${}^1{S}_0$.
