Deformed Special Relativity from Asymptotically Safe Gravity

TL;DR

This paper explores how a minimal length scale in asymptotically safe gravity leads to a natural emergence of deformed special relativity, analyzing its interpretation through thought experiments and comparing it to other DSR models.

Contribution

It demonstrates that a version of deformed special relativity naturally arises from asymptotically safe gravity, providing new insights into quantum gravity phenomenology.

Findings

Deformed special relativity emerges from asymptotically safe gravity.

Thought experiments clarify the interpretation of DSR in this context.

Comparisons highlight similarities and differences with other DSR approaches.

Abstract

By studying the notion of a fundamentally minimal length scale in asymptotically safe gravity we find that a specific version of deformed special relativity (DSR) naturally arises in this approach. We then consider two thought experiments to examine the interpretation of the scenario and discuss similarities and differences to other approaches to DSR.
