Study of seasonal variations of the atmospheric neutrino flux with MCEq — •Patrick Heix, Pascal Backes, Jakob Böttcher, Philipp Fürst, Christian Haack, Jöran Stettner, Christopher Wiebusch, and Marit Zöcklein for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen

Atmospheric muon neutrinos originate mostly from the decay of pions and kaons in atmospheric showers initiated by cosmic rays. The production rate of these neutrinos depends on the profiles of density and temperature of the atmosphere. Using the Matrix Cascade Equation (MCEq) code, we calculate the neutrino flux for different atmospheric profiles, varying hadronic interaction and cosmic ray models. In particular we study the impact of these parameters on the seasonal variation of the atmospheric neutrino flux.
