Abstract
[en] This thesis independently reproduces and solves the neutrino propagation equations to analyze how a hypothetical Z' boson affects very-high-energy astrophysical neutrinos. It aims at taking into account until-now discarded matter potentials in the analysis. The study evaluates two distinct scenarios: a light mediator regime (where absorption and matter effects overlap) and a heavy mediator regime (where only matter effects occur). Ultimately the results are negative: showing that to observe significant matter potentials signatures, one either needs self-defeating or beyond-experimental-bounds (KATRIN) overdensities.
