Polarization observables of the gamma d --> PiNN reaction in the Delta(1232)-resonance region

Abstract

Polarization observables of the three charge states of the pion for the $γd\toπNN$ reaction with polarized photon beam and/or oriented deuteron target are evaluated over the whole $Δ$(1232)-resonance region adopting a nonrelativistic model based on time-ordered perturbation theory. Results for the $π$-meson spectra, linear photon asymmetry, vector and tensor target asymmetries are presented. Particular attention is given, for the first time, to double polarization asymmetries for which we present results for $T_{20}^{\ell}$ and $T_{2\pm 2}^{\ell}$. We found that all other double polarization asymmetries of photon and deuteron target are vanished.
