WG1: Theoretical frameworks for gravity effects below the Planck energy

Contacts | Objectives |Tasks | Milestones | Members | Talks | Related works| Getting Involved


Group Leader: Christian Pfeifer (ZARM, University of Bremen)
Group Vice-Leader: Giulia Gubitosi (University of Burgos, Spain)


Development and extension of theoretical frameworks, from doubly special relativity (DSR), standard model extensions (SME), non-local/non-commutative effective field theory (EFT) and modified dispersion relations, to quantum-gravity-induced black hole mimickers and Finsler geometries, aiming at describing possible scenarios for low energy (sub-Planckian) effects induced by quantum gravity theories.


  • Improve the mathematical consistency and our physical understanding of these models, in order to bring them to the level of development that is necessary to provide reliable predictions and admit experimental constraints.
  • Determine how experimentally-accessible observables are derived from the fundamental assumptions of the different models; in particular, how to describe observers, their measurements and measurement comparison in the presence of LIV or DSR scenarios.
  • Identify equations which connect the sub-Planckian theories to fundamental approaches to quantum gravity.
  • Determine how experimentally-accessible observables are derived from the fundamental assumptions of the different models; in particular, how to describe observers, their measurements and measurement comparison in the presence of LIV or DSR scenarios.


  • Compile a comprehensive review of existing theoretical frameworks for QG phenomenology
  • Organise a workshop bringing together people working on fundamental QG theories and QG phenomenology.

Joint WG1-WG2 deliverables and activities

  • Publication of at least 8 papers per year in major, high impact, international journals.
  • A comprehensive wrap-up report of each year’s progress and insights.
  • Organization of regular video conferences/visits
  • Organization of workshops for specific topics involving also WG3-6
  • Publication of results of studies in the webpage.
