Flavor and magnetic field effects in GRB neutrino fluxes — •Philipp Baerwald, Svenja Hümmer, and Walter Winter — Institut für theoretische Physik und Astrophysik, Universität Würzburg, Am Hubland, D-97074 Würzburg, Germany

We present a novel approach to calculate neutrino spectra from cosmic accelerators. As a first step we demonstrate that we can reproduce the Waxman-Bahcall flux shape of Gamma-Ray Burst neutrinos from first principles. From this basis we show how the flux shape is changed by using the full photohadronic interaction cross section and by the introduction of flavor mixing. In the final step we illustrate how the highly variable parameters of a GRB affect the expected neutrino spectra.
