Description
The flavor composition of high-energy neutrinos carries important information about their birth. However, the two most common production scenarios, $pp$ and $p\gamma$ collisions, lead to the same flavor ratio when neutrinos and antineutrinos are indistinguishable. The Glashow resonant interaction $\bar{\nu}_e+e^- \rightarrow W^-$ becomes a window to differentiate the antineutrino contribution from the total diffuse neutrino flux, thus lifting this degeneracy. In this talk, I will discuss the power of Glashow resonant events in measuring the fraction of the $\bar{\nu}_e$ flux with current IceCube data, and the projected sensitivities based on the combined exposure of next-generation Cherenkov neutrino telescopes around the globe.
