Bounds on an Energy-Dependent and Observer-Independent Speed of Light from Violations of Locality
Abstract
We show that models with deformations of special relativity that have an energy-dependent speed of light have nonlocal effects. The requirement that the arising nonlocality is not in conflict with known particle physics allows us to derive strong bounds on deformations of special relativity and rule out a modification to first order in energy over the Planck mass.
