  "abstract": "Planck-scale departures from special relativity are commonly described by theories that break Lorentz symmetry and theories in which such symmetry is deformed. We prove that, under a global shell-linearizability condition, these two descriptions are physically equivalent for a single particle, corresponding to unitarily equivalent realizations of the same Wigner orbit expressed in different momentum coordinates. This equivalence breaks down for multiparticle systems, except when the momentum-composition law can be reduced to the ordinary addition of momenta. Our results imply that the distinction between Lorentz violating and Lorentz-deformed kinematics can only be tested by genuine multiparticle observables. We discuss Compton edge measurements as a prototype example of such a multiparticle probe.",
