Limiting the Parameter Space for Unstable eV-Scale Neutrinos Using IceCube Data

R. Abbasi et al. (IceCube Collaboration)

Abstract

Author(s): R. Abbasi et al. (IceCube Collaboration) This Letter extends a recent IceCube sterile neutrino search to include unstable sterile neutrinos within the context of a model termed

3 + 1 + D ec a y

, which expands upon the

3 + 1

model by introducing sterile neutrino decay to invisible particles with coupling constant

g^{2}

. The model is… [Phys. Rev. Lett. 137, 101801] Published Wed Sep 02, 2026
