Asymptotic approach to Special Relativity compatible with a relativistic principle

Understand

We propose a general framework to describe Planckian deviations from Special Relativity (SR) compatible with a relativistic principle.

• They are introduced as the leading corrections in an asymptotic approach to SR going beyond the energy power expansion of effective field theories.
• We discuss the conditions in which these Planckian effects might be experimentally observable in the near future, together with the non-trivial limits of applicability of this asymptotic approach that such a situation would produce, both at the very high (ultraviolet) and the very low (infrared) energy regimes.
