    "abstract": "The role of the final-state $NN$-rescattering ($NN$-FSI) in the polarization\nobservables of the inclusive reaction $d(\\gamma,\\pi^-)pp$, involving\npolarization of the photon beam and/or the deuteron target, is investigated.\nVarious single- and double-spin asymmetries are studied with respect to the\ninfluence of such interaction effect and numerical predictions are given for\nforthcoming experiments. It has been found that the effect of $NN$-FSI is quite\nimportant for the single-spin asymmetries $\\Sigma$, $T_{20}$, $T_{21}$ and\n$T_{22}$ and the double-spin asymmetry $T^{\\ell}_{20}$, whereas it is much less\nimportant for the vector target asymmetry $T_{11}$ and other beam-target\ndouble-polarization asymmetries. Furthermore, we found that the inclusion of\nthe $NN$-FSI improves the description of the LEGS data for the linear photon\nasymmetry.",
