    "abstract": "We define affine transport lifts on the tangent bundle by associating a\ntransport rule for tangent vectors with a vector field on the base manifold.\nThe aim is to develop tools for the study of kinetic/ dynamical symmetries in\nrelativistic particle motion. The transport lift unifies and generalises the\nvarious existing lifted vector fields, with clear geometric interpretations. We\nfind the affine dynamical symmetries of free particle motion, and compare this\nto previous results and to the alternative concept of \"matter symmetry\".",
