    "abstract": "Particle systems admit a variety of tensor product structures (TPSs)\ndepending on the complete system of commuting observables chosen for the\nanalysis. Different notions of entanglement are associated with these different\nTPSs. Global symmetry transformations and dynamical transformations factor into\nproducts of local unitary operators with respect to certain TPSs and not with\nrespect to others. Symmetry-invariant and dynamical-invariant TPSs and\ncorresponding measures of entanglement are defined for particle scattering\nsystems.",
