| Abstract: | Extensive air showers produce high-energy muons that can be utilized to probe hadronic interaction models in cosmic ray interactions. Most muons originate from pion and kaon decays, called conventional muons, while a smaller fraction, referred to as prompt muons, arises from the decay of heavier, short-lived hadrons. The EHISTORY option of the air shower simulation tool CORSIKA7 is used in this work to investigate the prompt and conventional muon flux in the energy range of 100 TeV – 100 PeV , utilizing the newly developed open-source python software PANAMA. Identifying the muon parent particles allows for scaling the contribution of prompt particles, which can be leveraged by future experimental analyses to measure the normalization of the prompt muon flux. Obtained prompt muon spectra from CORSIKA7 are compared to MCEq results. The relevance to large-volume neutrino detectors, such as IceCube and KM3NeT, and the connection to hadronic interaction models is discussed. [ABSTRACT FROM AUTHOR] |
