Group Leader: Flavio Mercati (University of Naples, Italy)
Group Vice-Leader: Stefano Liberati (SISSA, Italy)

Objectives

Study the influence of the models constructed in WG1 on the observables seen by WG3-WG6. Develop a parametrization of possible effects for systematic comparison between theory and experiment, similarly to what is accomplished by the Parametrized Post-Newtonian (PPN) formalism for General Relativity (GR) and modified/extended theories of gravity. Systematically derive, from the experimental results coming from the different messengers, constraints on the theoretical models, and combine these constraints into a consistent picture. Develop a phenomenology of multi-messenger events and identify the theoretical predictions/models for which these events offer improved constraining power.

Tasks

Develop and set up a systematic scheme to identify, in the experimentally-accessible observables, quantum gravity effects such as: unexpected time delays, anomalous frequency dependencies, deviations from general relativistic particle trajectories, modifications to the dynamics of black hole mergers and other GW sources, irreducible noise in precision measurements, QG-induced decoherence, violations of CPT symmetry and/or matter-antimatter asymmetry, modifications of astrophysical thresholds, and others. Introduce parameters connected to the different effects and predict the values of the parameters from the theoretical models. Clearly differentiate between effects due to quantum gravity and effects due to the physics of the sources of the observables. Use the data provided by the experiment to determine the value of the theoretically-calculated parameters, and provide feedback to the theorists to guide further theoretical developments.

Milestones

Development of a suitable parametrization for describing QG induced phenomenological effects. Derivation of the values of the parameters in the models discussed in WG1. Establishment of the experimental constraints on these parameters from experiments with WG3-6. Publication of the results and dissemination in workshops and conferences.

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.
