“…Upcoming studies of diffraction at the LHC, including those with a nuclear target [16,55], will reduce the model uncertainty for the first interaction to its minimum. To further improve the models it is important to take into account that the air shower measurements, such as the muon production depth, can also give very strong constraints on hadronic interactions in particular for pion interactions [53] for which cumulative effects due to the hadronic cascade are observed.…”

“…On the other hand, since the number of particles in an air shower is roughly proportional to the energy of the primary particle, the most energetic outgoing particles of an interaction, emitted in the very forward region of a collider experiment -such as in diffractive interactions -are the most important ones for understanding air showers. For the first time at the LHC, collider experiments include a large variety of forward detectors to study forward particle and energy spectra which have a direct impact on air shower development [16]. These latest measurements are not yet taken into account in the available hadronic interactions models, but are very important to understand the open issues in these models and for their future developments.…”

In detailed air shower simulations, the uncertainty in the prediction of shower observable for different primary particles and energies is currently dominated by differences between hadronic interaction models. With the results of the first run of the LHC, the difference between post-LHC model predictions has been reduced at the same level as experimental uncertainties of cosmic ray experiments. At the same time new types of air shower observables, like the muon production depth, have been measured, adding new constraints on hadronic models. Currently no model is able to reproduce consistently all mass composition measurements possible with the Pierre Auger Observatory for instance. We review the current model predictions for various particle production observables and their link with air shower observables and discuss the future possible improvements.

Hadronic interaction models are extensively tested using the LHC data since its beginning in 2009. The paper reviews the LHC results relevant to air shower modeling. Measurements of forward particle productions are especially focused because they carry a large fraction of collision energy. The paper reviews not only the LHC results, but also covers a fixed-target experiment and a lower energy collider experiment. A future possibility of LHC light-ion collisions is also discussed.

“…It is expected that they will provide much more detailed and precise measurements of hard diffraction in various topologies. The forward physics programme for the LHC including feasibility studies for many processes can be found in the report [9] prepared by a dedicated Forward Physics and Diffraction Working Group.…”
