Description

Overview

The common theoretical scheme for Gravity and Quantum Mechanics, still a work in progress, may induce quantum effects in the space-time structure at Planck scale (e.g. space-time foam) which would result in an energy dependent speed of light, in a contradiction to the Einstein’s theories of Relativity. This would imply that the Lorentz Invariance is not an exact symmetry of vacuum. Various ways may lead to Lorentz Invariance Violation (LIV) within different frameworks: String Theories, Loop Quantum Gravity, non-commutative geometry or modified Special Relativity.

The workshop will bring together experimentalists and theoreticians working on quantum spacetime and the LIV physics area. During two days, the latest results on LIV (time of flight studies, fuzziness, etc.) obtained with all major ground based and satellite gamma-ray detectors and different kind of astrophysical sources (GRBs, AGNs and Pulsars) will be reviewed. Some analyses with other messengers (neutrinos, gravitational waves) will also be addressed. In addition, recent progress on the theoretical side relevant to quantum spacetime, LIV studies and connections to the Quantum Gravity models will be discussed. Finally, the potential of future experiments will be addressed, focusing on the Cherenkov Telescope Array (CTA) and all major space-based experiments.
