Prof. Francis Halzen (University of Wisconsin Madison)25/09/2017, 10:20High-energy neutrino observations and perspectivesTalk (20'+5')The IceCube project has transformed a cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects more than 100,000 neutrinos per year in the GeV-to-PeV energy range. Among those, we have isolated a flux of high-energy cosmic neutrinos. I will discuss the latest measurements of the cosmic neutrino flux and their implications for its possible origin(s). From the...Go to contribution page

Dr Rikard Enberg (Uppsala University)25/09/2017, 13:55Astrophysical sources and backgroundsTalk (20'+5')The atmospheric neutrino flux is produced when cosmic rays collide with Earth's atmosphere. At very high energy, the prompt contribution to the neutrino flux, which comes from decays of charmed hadrons, dominates over the conventional flux, which comes from pion and kaon decays. This is due to the very short lifetime of the charmed hadrons, which therefore do not lose energy before they decay....Go to contribution page

Prof. Alexander Kusenko (UCLA and Kavli IPMU)25/09/2017, 15:10Observed spectra of distant blazars show evidence of secondary gamma rays from interactions of cosmic rays with extragalactic photon radiation (EBL and CMB). The same interactions of cosmic rays are expected to produce a flux of neutrinos with energies peaked around 1 PeV. The spectrum and the isotropic distribution are consistent with IceCube observations. This association also implies that...Go to contribution page

Giuseppe Di Sciascio (ROMA2)25/09/2017, 16:40Multimessenger physicsTalk (20'+5')The riddle of the origin of Cosmic Rays is unsolved since more than one century. The identification of the galactic sources able to accelerate particles beyond PeV energies is certainly one of the main open problems of high energy astrophysics.
