# Conservation laws and scattering for de Sitter classical particles

@article{Cacciatori2007ConservationLA, title={Conservation laws and scattering for de Sitter classical particles}, author={Sergio Luigi Cacciatori and Vittorio Gorini and Alexander Yu. Kamenshchik and Ugo Moschella}, journal={Classical and Quantum Gravity}, year={2007}, volume={25}, pages={075008-075008} }

Starting from an intrinsic geometric characterization of de Sitter timelike and lightlike geodesics we give a new description of the conserved quantities associated with classical free particles on the de Sitter manifold. These quantities allow for a natural discussion of classical pointlike scattering and decay processes. We also provide an intrinsic definition of the energy of a classical de Sitter particle and discuss its different expressions in various local coordinate systems and their… Expand
