Light gauge bosons can lead to resonant interactions between high-energy astrophysical neutrinos and the cosmic neutrino background. We study this possibility in detail, considering the ability of IceCube to probe such scenarios. We find the most dramatic effects in models with a very light Z (m Z < ∼ 10 MeV), which can induce a significant absorption feature at Eν ∼ 5-10 TeV × (m Z /MeV) 2 . In the case of the inverted hierarchy and a small sum of neutrino masses, such a light Z can result in a broad and deep spectral feature at ∼ 0.1-10 PeV × (m Z /MeV) 2 . Current IceCube data already excludes this case for a Z lighter than a few MeV and couplings greater than g ∼ 10 −4 . We emphasize that the ratio of neutrino flavors observed by IceCube can be used to further increase their sensitivity to Z models and to other exotic physics scenarios.

“…These observations also make it possible to study interactions between high-energy neutrinos and the cosmic ray neutrino background (CνB). In particular, scenarios featuring a light gauge boson have received some recent attention within this context [26][27][28][29][30][31][32][33][34].…”
