Talk Title: "Ultra-high energy neutrino events at the IceCube and the Glashow resonance"

Abstract: 

The Glashow resonance is a peak of enhanced cross-section for an electron-anti-neutrino of 6.3 PeV energy interacting with an electron and producing a resonant W boson, which further decays into electrons and hadrons producing cascades in a large volume (Km^3) neutrino detector such as the IceCube. We will explore the significance of this narrow bin of energy, generally with respect to ultra-high energy events in the IceCube, and particularly, in view of the two recently observed neutrino events at the PeV energies; we will show that the observation of (or lack of) events at 6.3 PeV energies in the future will allow us to understand several facets of the Ultra-high energy neutrino flux coming, possibly, from extra-galactic sources.
