Spacetime and deformations of special relativistic kinematics

Carmona, José Manuel (Universidad de Zaragoza) ; Cortés, José Luis (Universidad de Zaragoza) ; Relancio, José Javier (Universidad de Zaragoza)

Resumen: A deformation of special relativistic kinematics (possible signal of a theory of quantum gravity at low energies) leads to a modification of the notion of spacetime. At the classical level, this modification is required when one considers a model including single- or multi-interaction processes, for which absolute locality in terms of canonical spacetime coordinates is lost. We discuss the different alternatives for observable effects in the propagation of a particle over very large distances that emerge from the new notion of spacetime. A central ingredient in the discussion is the cluster decomposition principle, which can be used to favor some alternatives over the others.
