Abstract
Two years of IceCube data recorded between May 2010 and April 2012 have been analyzed in a search for neutrinos generated by ultra-high energetic cosmic rays at PeV to EeV energies. Two events with energies of about 1-10 PeV pass all selection criteria. At such energies it is unlikely that these events originate from neutrinos generated within cosmic-ray air showers by the decay of secondary pions and kaons. The talk describes the analysis and discusses possible interpretations of the result.
