A description of the intermediate and high energy hadronic interaction models
used in the FLUKA code is given. Benchmarking against experimental data is also
reported in order to validate the model performances. Finally the most recent
developments and perspectives for nucleus-nucleus interactions are described
together with some comparisons with experimental data.Comment: talk from the 2003 Computing in High Energy and Nuclear Physics
