The tensor analyzing power T20 in deuteron break-up reactions within the Bethe-Salpeter formalism

The tensor analyzing power T20 and the polarization transfer κ 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 T20, κ 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.
