I will review the physics of flavor transformations of supernova neutrinos. I will then discuss time dependent features in the neutrino signal caused by the changing density profile in the explosion.

I investigate the possibility of using icosahedral symmetry as a family symmetry group in the lepton sector, focusing on the intriguing hypothesis that the solar neutrino mixing angle is governed by the golden ratio. I will present a basic toolbox for model-building using icosahedral symmetry, including explicit representation matrices and tensor product rules. As a simple application, I...

Lorentz symmetry is a key feature of our best description of nature. Among the different tests of this fundamental symmetry are ones with neutrino oscillations, which can provide a sensitive measurement of suppressed signals of new physics. The talk describes the neutrino sector of the Standard-Model Extension, which represents a general modification of the standard neutrino massive model...

The OPERA experiment has been designed to prove the existence of nu_mu -> nu_tau oscillations in the atmospheric sector by the direct observation of nu_tau appearance in the CNGS nu_mu beam, produced at CERN.
The detector, installed at Laboratori Nazionali del Gran Sasso (Italy), 730 km away from the neutrino source, consists of a modular target made of lead - nuclear emulsion bricks...

OPERA is an experiment that aims at detecting the appearance of tau-neutrinos in an almost pure muon-neutrinos beam through oscillation. The CC tau-neutrino interaction is identified through the detection of the tau lepton decay topology in the so-called Emulsion Cloud Chambers (ECC), passive lead sheets constituting the target mass interleaved with nuclear emulsion films providing the high...

Since its 2007 electron neutrino search result in 2007, the MiniBooNE collaboration has continued to press forward with additional neutrino and antineutrino running, an expanded investigation of the low energy excess seen in its first results, appearance and disappearance analyses in both neutrino and antineutrino data samples, and an array of unprecedented cross-section measurements. This...

The production of single photons in low energy (~1 GeV) neutrino scattering off nucleons is analyzed in the Standard Model. At very low energies, E(nu) << 1 GeV, a simple description of the chiral lagrangian involving baryons and arbitrary SU(2)_L x U(1)_Y gauge fields is developed. Extrapolation of the process into the ~1-2 GeV region is treated in a simple phenomenological model. Coherent...

Low energy photon production is an important background to many current and future precision neutrino experiments. I present a phenomenological study of t-channel radiative corrections to neutral current neutrino nucleus scattering. After introducing the relevant processes and phenomenological coupling constants, I will explore the derived energy and angular distributions as well as total...

The Daya Bay Reactor Anti-Neutrino Experiment is a neutrino oscillation experiment designed to observe and measure the neutrino mixing angle θ13. The sensitivity goal is 0.01 in sin^2(2θ13) at the 90% confidence level, a significant improvement over the current limit. This will be accomplished by measuring the relative rates and energy spectra of reactor electron antineutrinos with multiple...

Search for $\theta_{13}$, the last unknown mixing angle is extreamly important in
understanding the lepton flavor mixing matrix, and investigation of the CP violation
in the lepton sector. The reactor neutrino experiments can provide a clean laboratory
for the $\theta_{13}$ measurement via electron antineutrino disappearance.
The Daya Bay experiment proposes to measure...
