Abstract

We study neutrino conversions in a recently envisaged source of high-energy neutrinos (E ≥ 106 GeV), that is, in the vicinity of cosmological Gamma-Ray Burst fireballs (GRB). We consider the effects of flavor and spin-flavor conversions and point out that in both situations, a some what higher than estimated high energy tau neutrino flux from GRBs is expected in new km2 surface area under water/ice neutrino telescopes.
