Measurements of the muon content of extensive air showers at the highest energies show large discrepancies compared to simulations. This so-called muon puzzle is commonly attributed to a lack of understanding of the hadronic interactions in the shower development. Furthermore, measurements of the fluctuations of muon numbers suggest that the discrepancy is likely a cumulative effect of interactions of all energies in the cascade.
With the newly developed "history" extension of the air shower simulation code CORSIKA 8 we are able to relate interactions happening at any intermediate stage in the cascade to the final-state muons. With this technique we study "muon-number weighted" particle distributions of hadronic interactions in order to quantify the relevance of different phase space regions for muon production.
