The Tensor Analyzing Power T20 in Deuteron Break-up Reactions within the Bethe-Salpeter Formalism

The tenser analyzing power T-20 and the polarization transfer kappa in the deuteron break-up reaction Dp --> pX are calculated within a relativistic approach based on the Bethe-Salpeter equation with a realistic meson-exchange potential. Our results on T-20, kappa and the cross section are compared with experimental data and non-relativistic calculations and with the outcome of a relativization procedure of the deuteron wave function.
