Spin observables for pion photoproduction on the deuteron in the $\Delta$(1232)-resonance region

Abstract

Spin observables for the three charge states of the pion for the pion photoproduction reaction on the deuteron, $\gamma d\to \pi NN$, with polarized photon beam and/or oriented deuteron target are predicted. For the beam-target double-spin asymmetries, it is found that only the longitudinal asymmetries $T_{20}^{\ell }$ and $T_{2\pm 2}^{\ell }$ do not vanish, whereas all the circular and the other longitudinal asymmetries do vanish. The sensitivity of spin observables to the model deuteron wave function is investigated. It has been found that only $T_{21}$ and $T_{22}$ are sensitive to the model deuteron wave function, in particular in the case of ${\pi }^0$-production above the $\Delta$-region, and that other asymmetries are not.
