| Description |
I will discuss the potential sources of high energy neutrinos and the different efforts made to detect them. The possibility that the two PeV neutrinos recently observed by IceCube are produced by the interactions of extragalactic cosmic rays during their propagation through the radiation backgrounds will be analysed, as well as the actual relevance of the Glashow resonance for their detection. The complementary aspects of cosmic ray, neutrino and gamma searches will be discussed. |
