Description
By colliding protons with oxygen ions, the LHC enables studies of fundamental properties of matter at extraordinary range of energy scales of ~10 TeV. The recent p+O collisions at the LHC reproduce key features of PeV cosmic-ray interactions with the Earth’s atmosphere. Interpreting data from ground-based cosmic-ray detectors relies on detailed simulations of hadronic interactions at TeV-scale center-of-mass energies. These simulations are based on phenomenological models that require tuning to collider data, particularly in the forward and high-energy regimes. This talk presents the first measurement of prompt charged-particle production in proton–oxygen collisions at $\sqrt{s_{NN}}$=9.62 TeV, delivering key constraints for tuning the hadronic models and aiding the development of cosmic-ray air showers generators.
