Deutron Break-Up: Theoretical Description of Polarization Observables in Stapp formalism

Abstract

The vector and tensor analyzing powers as well as the polarization of the outgoing proton are calculated for the exclusive deuteron break-up reaction $\vec{d}p\to \vec{p}pn$ at a deuteron beam energy of 2 GeV. Two component covariant formalism of Stapp has been used to have the completely Lorentz invariant model. In addition to the Impulse Approximation the nucleon-nucleon double-scattering and delta-excitation mechanism have been added coherently. Good agreement with the precise data obtained at Saclay is achieved.
