Description
Accurately modeling the atmospheric lepton fluxes plays a crucial role for astrophysical neutrino search, neutrino oscillations studies, probing hadronic interaction models, beyond-standard-model searches, and tools such as muon tomography. In this talk, I present the latest update of the flux modeling code MCEq (Matrix Cascade Equations), featuring an updated particle yield and cross-section database supporting the most recent generation of hadronic interaction models SIBYLL-2.3e, EPOS-LHC-R, and QGSJet-III. Using MCEq and MUTE (MUon inTensity codE) I demonstrate the frameworks application to seasonal variation studies and compare its aspects with the common $\alpha_T$ approach. Furthermore, future applications and advanced flux modeling for MCEq are outlined.
