TY - CONF A1 - Ostapchenko, Sergey T1 - High energy cosmic ray interactions and UHECR composition problem T2 - EPJ Web of Conferences N2 - The differences between contemporary Monte Carlo generators of high energy hadronic interactions are discussed and their impact on the interpretation of experimental data on ultra-high energy cosmic rays (UHECRs) is studied. Key directions for further model improvements are outlined. The prospect for a coherent interpretation of the data in terms of the UHECR composition is investigated.
