Objectives (shared with WG4, WG5 and WG6)
To analyze the current state of the art of the experimental astronomy of each type of cosmic messenger with respect to the Action’s challenge and identify opportunities for improving the analysis strategies which are currently being followed, in the light of the theoretical frameworks and considerations of WG1 and WG2. To provide WG1 and WG2 with the technical details related to the detection of each type of astrophysical messenger, which need to be considered for a correct phenomenological and theoretical interpretation of the experimental results. To develop new analysis strategies that combine the observations of gamma rays, cosmic rays, neutrinos and gravitational waves for the search of quantum gravity signatures in the framework of multi-messenger astronomy. These new
strategies should be developed in close cooperation with WG1 and specially with WG2. Finally, these WGs will transfer the Action’s motivations, progress and results, to their respective communities of experimentalists to promote their interest on the Action’s challenge.
Tasks
- Tackle the problem of the possibility of observing quantum gravity (QG) effects in the propagation of ultra-high-energy cosmic rays (UHECRs), given the experimental observation of a high-energy suppression in the all-particle spectrum
- Consider the implications of QG phenomenology in the extragalactic electromagnetic cascades produced in the propagation of UHECRs, clarifying the different implications of Lorentz invariance violation (LIV) and deformed special relativity (DSR) frameworks
- Study the effects of QG phenomenology on the production processes of UHECRs, also relating the observed spectrum with that of the (possible) associated messengers (e.g. neutrinos and gamma rays)
- Consider the possibility of deriving limits for LIV and DSR parameters from the modifications in the development of the extensive air showers initiated by high-energy cosmic rays in the Earth’s atmosphere, also relating these effects to the excess of muons in observed air showers as compared to simulations.
Milestones
- Year 1: Review, improve and update the already existing searches for quantum gravity signatures through cosmic rays measurements.
- Year 2: Constrain QG phenomenology from the available experimental data in the different cases of LIV and DSR.
- Year 3: Definition of new analysis strategies taking into account the theoretical frameworks developed in WG1 and WG2.
- Year 4: Development of multi-messenger search strategies based on the phenomenological models developed by WG1 and WG2.
Joint WG3-WG4-WG5-WG6 deliverables and activities
- Publicly available web page with results of LIV studies based on each cosmic messenger.
- Optimal strategy and method for performing LIV studies (including future experiments and a multi-messenger approach).
- Publications, and contributions to conferences.
- Contributions to the communication and outreach activities.
- Organization of regular video conferences
- Organization of workshops for specific topics involving also WG1-2
