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

The vector A y and tensor A yy analyzing powers as well as the polarization of the outgoing proton are calculated for the exclusive deuteron break-up reaction ~dp → ~ppn 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 .
