Oscillation of nu_mu to nu_e driven by non-zero theta_13 mixing angle is expected to be influenced by matter effect, especially in the multi-GeV energy region. Since matter effect occurs on either neutrino or anti-neutrino depending on mass hierarchy, it is possible to deduce mass hierarchy by investigating nu_e oscillation separately for neutrino and anti-neutrino. In this talk, we will...

With its low-energy extension DeepCore, the IceCube Neutrino Observatory at the geographic South Pole is able to identify neutrino events with energies as low as 10 GeV. This permits investigation of the oscillations of atmospheric muon neutrinos by observing their zenith angle and energy dependent disappearance. Maximum disappearance is expected for vertically upward moving...

We present new limits on mixing between active and sterile neutrinos using more than 11 years of atmospheric data from the Super Kamiokande experiment. SuperK observes neutrinos over a wide range of energies and path lengths, allowing us to search for sterile neutrino signatures that are independent of theoretical ambiguities such as the precise new mass splitting or the number of sterile...

KM3NeT aims at the construction of a high energy neutrino telescope in the Mediterranean Sea. Due to its location and its large size (several km3) it is the optimal instrument to investigate neutrinos from the Southern sky and in particular from the Galactic plane, thus making it complementary to IceCube. The initial, EU-funded stages (Design Study and Preparatory Phase Study) have been...

Low-Energy Neutrinos (solar, reactor, supernova, and geo neutrinos and also nuclear astrophysics associated with these sources)
Supernova neutrinos experience self-induced flavor conversions associated with the neutrino-neutrino interactions in the deepest stellar regions. In this context, we perferm the first numerical simulations of the self-induced neutrino evolution incluing the azimuthal angle of neutrino propagation as an explicit variable. Without enforcing the axial symmetry of the solution, we find that new...
