Loop Quantum Gravity Phenomenology: Linking Loops to Observational Physics

Understand

Research during the last decade demonstrates that effects originating on the Planck scale are currently being tested in multiple observational contexts.

• In this review we discuss quantum gravity phenomenological models and their possible links to loop quantum gravity.
• Particle frameworks, including kinematic models, broken and deformed Poincar\'e symmetry, non-commutative geometry, relative locality and generalized uncertainty principle, and field theory frameworks, including Lorentz violating operators in effective field theory and non-commutative field theory, are discussed.
• The arguments relating loop quantum gravity to models with modified dispersion relations are reviewed, as well as, arguments supporting the preservation of local Lorentz invariance.
