    "abstract": "This paper explores the connections between particle scattering and quantum\ninformation theory in the context of the non-relativistic, elastic scattering\nof two spin-1/2 particles. An untangled, pure, two-particle in-state is evolved\nby an S-matrix that respects certain symmetries and the entanglement of the\npure out-state is measured. The analysis is phrased in terms of unitary,\nirreducible representations (UIRs) of the symmetry group in question, either\nthe rotation group for the spin degrees of freedom or the Galilean group for\nnon-relativistic particles. Entanglement may occurs when multiple UIRs appear\nin the direct sum decomposition of the direct product in-state, but it also\ndepends of the scattering phase shifts. \\keywords{dynamical entanglement,\nscattering, Clebsch-Gordan methods}",
