Towards a new approach to quantum gravity phenomenology

TL;DR

This paper explores an alternative approach to quantum gravity phenomenology that does not rely on Lorentz invariance violation, addressing theoretical and experimental challenges in detecting quantum gravity effects.

Contribution

It proposes a new perspective on quantum gravity phenomenology, moving beyond Lorentz invariance violation and discussing potential theoretical connections and experimental challenges.

Findings

Lorentz invariance violation is strongly constrained and problematic.

An alternative phenomenological approach is proposed.

Challenges in experimental detection are outlined.

Abstract

The idea that quantum gravity manifestations would be associated with a violation of Lorentz invariance is very strongly bounded and faces serious theoretical challenges. This leads us to consider an alternative line of thought for such phenomenological search. We discuss the underlying viewpoint and briefly mention its possible connections with current theoretical ideas. We also outline the challenges that the experimental search of the effects would seem to entail.
