The Dark Matter Particle Explorer (DAMPE) is an ongoing space-borne experiment for the direct detection of cosmic rays (CR). Thanks to its large geometric acceptance and thick calorimeter, DAMPE is able to detect CR ions up to unprecedented energies of hundreds of TeV. Following by now more than 8 years of successful operation, DAMPE has amassed a large dataset of high-energy hadronic...

Thanks to the experimental advancements in the field of ultra-high-energy cosmic rays (UHECRs), recent results about their mass composition indicate that, as the energy increases, the mean mass of these nuclei first decreases, reaching its lightest point around 2 EeV, and then afterward, increases significantly.

These results motivated several studies for modelling the interactions...

12. Measurement of the proton-proton cross section at ultra-high energies with the Pierre Auger Observatory [10'+5']

The energies of cosmic rays significantly exceed the range of the existing human-made particle accelerators. The analysis of the air shower data makes it possible to infer the particle production cross sections - one of the most fundamental properties of soft QCD interactions at the highest energies. The depth at which the number of particles in a shower reaches its maximum is linked to the...

52. Photonuclear cross sections and UHECR transport: towards more transparency [10'+5']

Studies of the origin and composition of ultra-high-energy cosmic rays involve simulating their interactions, predominantly with surrounding photon fields and involving photonuclear cross sections in the MeV-GeV range. Although such interactions within the source and during extra-galactic propagation are analogous, these scenarios are addressed separately and the codes employed for each of...
