Abstract
If the ordinary neutrinos oscillate into a sterile flavor in a manner consistent with the Super-Kamiokande data on the zenith-angle dependence of atmospheric μ-neutrino flux, an energy sufficient to power a typical cosmic gamma-ray burst (GRB) (~1052 ergs) can be carried away from the source by sterile neutrinos and deposited in a region relatively free of baryons. Hence, ultrarelativistic bulk motion (required by the theory and observations of GRBs and their afterglows) can be achieved in the vicinity of plausible sources of GRBs. Oscillations between sterile and ordinary neutrinos might, therefore, provide a solution to the "baryon-loading problem" in the theory of GRBs.Keywords
