Description
In 2023 the IceCube collaboration published the first observation of the Galactic diffuse neutrino flux. This emission is produced by cosmic rays interacting with the interstellar medium. The measurement of this flux can help to understand the distribution of cosmic rays in the Galaxy.
In this poster, we present plans for a new analysis combining different event topologies. IceCube measures events in two main topologies. Tracks, originating from charged current $\nu_\mu$ interactions, provide a good angular resolution. However, due to the large background from atmospheric muons, they are limited to the Northern Hemisphere. In contrast, cascades, which are produced in most other neutrino interactions, provide a good energy resolution and can observe the Southern sky (and therefore the Galactic Center). Combining both event topologies in one analysis exploits their respective advantages. Here, we discuss sensitivities of a combined measurement using a forward-folding binned likelihood analysis and its potential to discriminate between different theoretical models for the galactic diffuse neutrino flux.
