Description
Characteristic patterns of cosmic neutrino spectrum reported by the IceCube
Collaboration and long-standing inconsistency between theory and experiment
in muon anomalous magnetic moment are simultaneously explained by an extra
leptonic force mediated by a gauge field with a mass of the
MeV scale. With different assumptions for redshift distriution of
cosmic neutrino sources, diffuse neutrino flux is calculated with the
scattering between cosmic neutrino and cosmic neutrino back-ground through
the new leptonic force. Our analysis sheds light on a relation among lepton physics
at the three different scales, PeV, MeV, and eV, and provides possible clues to the distribution of sources of cosmic neutrino and also to neutrino mass spectrum
