Early decay of Peccei–Quinn fermion and the IceCube neutrino events

IceCube observed high-energy neutrino flux in the energy region from TeV to PeV. The decay of a massive long-lived particle in the early universe can be the origin of the IceCube neutrino events, which we call an “early decay scenario.” In this paper, we construct a particle physics model that conta...
