Description
The IceCube Neutrino Observatory has measured the high-energy astrophysical neutrino flux but has not yet detected prompt atmospheric neutrinos originating from charmed meson decays. Understanding the prompt neutrino flux is crucial for improving models of high-energy hadronic interactions and advancing astrophysical neutrino measurements. We present a combined analysis of cascades and up-going tracks to explore the subdominant prompt neutrino flux. We propose a robust method for calculating upper limits of the prompt flux, considering the model dependencies on the astrophysical and conventional atmospheric neutrino fluxes.
