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

27.11.2012

Sonderseminar: Atri Bhattacharya (Harish-Chandra Research Institute, Allahabad)

IceCube/Ishihara@Neutrino2012

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 (Km3) neutrino detector such as the IceCube. We will explore the significance of this narrow bin of energy in view of the two recently observed neutrino events at the PeV energies at the IceCube and 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.
