High energy neutrinos from charm in astrophysical sources

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We show that charm provides significant enhancement of the very high energy neutrino flux, when neutrinos originate in astrophysical sources with jets driven by central engines, such as gamma ray bursts or supernovae with jets. The neutrino flux from semi-leptonic decays of charmed mesons is subject to much less hadronic and radiative cooling than the conventional flux from pion and kaon decays and therefore has a dominant contribution at higher energies, of relevance to future ultrahigh energy neutrino experiments.
