Description
Quantum-gravity phenomenology is entering a more mature phase, especially thanks to the advent of multimessenger astrophysics. For in-vacuo dispersion by photons the CTA and multisatellite gamma-ray telescopes will soon provide data probing higher values of the magnitude of the effects and also suitable for discriminating between different models
of the redshift dependence of the effects. IceCube has opened a window on in-vacuo dispersion by neutrinos and tangible improvements in sensitivity will be achieved with KM3NeT, Baikal-GVD and IceCube-Gen2. For the study of Planck-sale-induced threshold anomalies telescopes such as LHAASO should ensure significant progress, by investigating indirectly the inconsistencies presently found among different estimates of the cosmic far-infrared background.The coming years should also bring about meaningful tests of phenomenological models of IR-UV mixing, thanks to improved astrophysics data and even higher accuracy of cold-atom interferometers.
This session is shared with the 4th Annual Conference COST CA18108 : Quantum gravity phenomenology in the multi-messenger approach.
