Abbasi, R.Hill, G.2013-04-092013-04-092011Physical Review Letters, 2011; 14(7):1-50031-90071079-7114http://hdl.handle.net/2440/76715IceCube has become the first neutrino telescope with a sensitivity below the TeV neutrino flux predicted from gamma-ray bursts if gamma-ray bursts are responsible for the observed cosmic-ray flux above 10¹⁸  eV. Two separate analyses using the half-complete IceCube detector, one a dedicated search for neutrinos from pγ interactions in the prompt phase of the gamma-ray burst fireball and the other a generic search for any neutrino emission from these sources over a wide range of energies and emission times, produced no evidence for neutrino emission, excluding prevailing models at 90% confidence.en© 2011 American Physical SocietyIceCube CollaborationJournal article002012242810.1103/PhysRevLett.106.1411010002893558000022-s2.0-7996063478722901
