COST CA18108 2nd Training School in Belgrade (Serbia), 3-10 September 2022

Our 2nd Training School will take place in Belgrade, Serbia, from the 3rd (starting in the afternoon) to the 10th September 2022. Registration is open at the website of the School:
where you can find additional information about the organization of the school.
We encourage the participation of PhD students and young postdocs with either theoretical or experimental background, since one of the objectives of the Action is the training of young researchers in theoretical models and experimental techniques in order to build a new scientific profile that will combine the relevant skills and a transversal background in the fields of astrophysics and quantum gravity.

Event: LHAASO discussion session
Date: 17th June 2021, from 9 to 13 h (CET time)


Discussion session organized by the COST Action CA18108 “Quantum gravity phenomenology in the multi-messenger approach” ( the revolutionary detection of 12 PeVatrons (sources of very high energy gamma-rays) that the LHAASO collaboration has recently announced (Zhen Cao, F.A. Aharonian et al., Ultrahigh-Energy Photons up to 1.4 Petaelectronvolts from 12 γ-Ray Galactic Sources, Nature 594, 7861 (2021)) and its impact, especially with respect to LIV searches (see e.g., C. Li and B.-Q. Ma, Ultrahigh-Energy Photons from LHAASO as Probes of Lorentz Symmetry Violations, arXiv:2105.07967), which is one of the key topics of research within our Action. 

– 9:00 CET: Felix Aharonian: PeVatrons, theory
– 9:45 CET: Zhen Cao: LHAASO experiment results
– 10:30 CET: Bo-Qiang Ma: LIV with LHAASO
– 11:15 CET: Free discussion
