摘要：Gamma-ray bursts (GRBs) are among the prime suspects as the sources of ultra-high energy (UHE) cosmic rays (CRs). It is believed that these sources are capable of accelerating nuclei to the extreme energies so far detected and are also able to supply enough power to sustain the energy density of UHE CRs. A smoking-gun signal of the acceleration of CRs in GRBs would be the emission of high-energy neutrinos from the decay of mesons that can be produced in photo-hadronic interactions in the presence of the burst or afterglow radiation. I will focus on the expected burst neutrino fluxes in the GRB fireball model. Recent results from the IceCube neutrino observatory on the emission of neutrinos from GRBs challenge the hypothesis that GRBs are the (main) sources of UHE CRs. I will summarize these results and their model implications.
