DESCRIPTION:Speakers: Stefan Fröse\n\nModeling atmospheric lepton fluxes 
 in cosmic ray cascades relies on our phenomenological understanding of had
 ronic interactions. While today's hadronic interaction models are tuned ag
 ainst collider data\, the cosmic-ray-induced interactions occur in forward
  kinematic regions inaccessible to collider experiments. In this talk\, I 
 present MCEq2\, a new generation of the Matrix Cascade Equations solver ca
 pable of computing multiple cosmic-ray arrival directions and atmospheric 
 profiles simultaneously while being significantly faster than its predeces
 sor. Building on this performance\, I show how seasonal variations of the 
 underground muon flux can be turned into a channel for constraining hadron
 ic interaction models\, providing an air-shower complement to collider dat
 a.\n\nhttps://indico.e5.physik.tu-dortmund.de/event/4509/
