Quantum-Spacetime Phenomenology

Giovanni Amelino-Camelia. Living Rev Relativ.

Abstract

I review the current status of phenomenological programs inspired by quantum-spacetime research. I stress in particular the significance of results establishing that certain data analyses provide sensitivity to effects introduced genuinely at the Planck scale. My main focus is on phenomenological programs that affect the directions taken by studies of quantum-spacetime theories.

Keywords: loop quantum gravity; quantum spacetime; spacetime noncommutativity.

Figures

Figure 1
Figure 1
The figure shows semi-quantitatively the expected unification of the coupling “constants” of the Standard Model of particle physics, and also shows a naive description (which, however, we are so far unable to improve upon) of the strength of gravitational interactions, obtained by dividing the Newton constant by the square of the length scale characteristic of the process.
