Query: Atmospheric muons from electromagnetic cascades   Atmospheric muons are one of the main backgrounds for current Water- and
Ice-Cherenkov neutrino telescopes designed to detect astrophysical neutrinos.
The inclusive fluxes of atmospheric muons and neutrinos from hadronic
interactions of cosmic rays have been extensively studied with Monte Carlo and
cascade equation methods, for example, CORSIKA and MCEq. However, the muons
that are pair produced in electromagnetic interaction of high energy photons
are quantitatively not well understood. We present new simulation results and
assess the model dependencies of the high-energy atmospheric muon flux
including those from electromagnetic interactions, using a new numerical
electromagnetic cascade equation solver EmCa that can be easily coupled with
the hadronic solver MCEq. Both codes are in active development with the
particular aim to become part of the next generation CORSIKA 8 air shower
simulation package. The combination of EmCa and MCEq accounts for material
effects that have not been previously included in most of the available codes.
Hence, the influence of these effects on the air showers will also be briefly
discussed.
