Description
Atmospheric neutrinos play a dual role in particle physics: they are crucial signals for studying neutrino oscillations and serve as significant backgrounds in searches for the diffuse supernova neutrino background, proton decay, dark matter, and other rare processes. To address unresolved questions in neutrino oscillation physics and to identify rare events, precise predictions of atmospheric neutrino flux in the GeV and lower energy ranges are essential. In this talk, I will present the latest results on the calculation of atmospheric neutrino fluxes at sites such as JUNO and Super-Kamiokande. The calculation scheme builds on the methods outlined in [Honda et al., Phys. Rev. D 92, 023004 (2015)], with enhancements to achieve greater precision, particularly in the low-energy regime.
