Observing astrophysical neutrinos provides a unique insight into the acceleration mechanism of cosmic ray sources: neutrinos can only be produced in hadronic interactions and are neither absorbed nor deflected, thus pointing back to their source. The talk will cover hints for an excess of neutrinos above the atmospheric spectrum seen in recent IceCube analyses and discuss the observation of...

Reactor neutrino experiments have now observed a nonzero value for \theta_{13} with a significance above 10-sigma. Nonzero values for theta_13 break a ν_μ-ν_τ symmetry, which has qualitative as well as quantitative implications for the time-evolution of neutrino flavors. In particular, the large-distance flavor evolution matrix, non-invertible with ν_μ-ν_τ symmetry, becomes invertible. This...

Neutrinos play important roles in revealing mechanisms of energetic
astrophysical explosions such as gamma-ray bursts (GRBs) and
supernovae (SNe). The large neutrino detector, IceCube has opened a new window of the multi-messenger astronomy. I review theoretical
models of high-energy neutrino emissions from gamma-ray bursts, with implications of recent observations and future prospects. I...

Theoretical evaluations of the high energy atmospheric neutrino and muon fluxes from cosmic ray interactions with air nuclei rely on calculations of charmed particle production and decay. Presented here is a review of approaches to charm contributions to the atmospheric lepton fluxes, including dipole models and the parton model with QCD.
