Collider and fixed-target experiments have achieved remarkably precise measurements of hadronic interactions, providing stringent tests of hadronic interaction models across a broad range of energies. In recent years, a new generation of space-based, ground-based, underground, and deep-ice/sea detectors—now in operation or under construction—has increasingly exploited cosmic-ray as natural particle beams, significantly expanding the experimental landscape. These experiments provide complementary and multi-dimensional insights into hadronic interaction processes, establishing cosmic-ray observations as a novel probe of hadronic interaction models.
This workshop aims to bring together experts from theoretical and experimental directions to discuss advances in hadronic interaction models, implications for cosmic-ray, dark matter and neutrino measurements, and emerging opportunities offered by next-generation experiments for improving our understanding of hadronic interactions. Particular emphasis will be placed on identifying shared benchmarks, observables, and validation strategies that can be jointly addressed by theorists and experimental collaborations.
Scientific topics:
- Hadronic interactions in heavy-ion collisions
