Abstract

The Glashow resonance at Eν=6.3PeV is a measure of the ν¯e content of the astrophysical neutrino flux. The fractional ν¯e content depends on the neutrino production model at the cosmic neutrino source, and the environment at the source. Thus, the strength of the Glashow resonance event rate is a potential window into astrophysical sources. We quantify the “Glashow resonometer” and comment on the significance that no Glashow events are observed in the IceCube three-year data.
