The effects are very small but much greater than the naive estimate $\Delta m^2/E_\nu^2$ or the branching ratio of indirect flavor violating processes such as
$\mu\rightarrow e\gamma$ within the SM.

Coherent neutrino-nucleus scattering (CNS) is an as-yet undetected, flavor-independent neutrino interaction predicted by the Standard Model.

The Daya Bay Reactor Neutrino Experiment is expected to measure $\sin^{2}(2\theta_{13})$ to 0.01 or better by performing a relative measurement of flux and energy spectrum of antineutrinos observed with inverse β decay events in the near and far antineutrino detectors. The antineutrino detectors will be placed in water pools and surrounded by at least 2.5m of water to suppress background. The...

The recent commissioning of the full DeepCore sub-array, a low-energy extension of the IceCube neutrino observatory, offers exciting opportunities for neutrino physics in the energy region of 10 GeV to 1 TeV. The improved energy reach, use of the surrounding IceCube detector as an active veto and immense size of DeepCore will produce one of the largest all-sky neutrino datasets ever acquired. ...

to search for neutrinoless double beta decay of Ge-76. In addition to the detectors deployed in Phase I, the Phase II of the experiment will use new detectors from 37.5 kg of enriched germanium with additional rejection capabilities. Possible candidates are p-type Broad Energy Germanium detectors (BEGe) or 18-fold segmented...

We propose a novel technique by which the energy spectrum of low energy electrons can be extracted. The technique relies on the detection and measurement of coherent radiation created from the cyclotron motion of electrons in strong magnetic fields. Since the frequency of cyclotron radiation emitted by the particle depends inversely on its Lorentz boost, the detection and measurement of the...

GUT monopoles captured by the Sun's gravitation are expected to catalyze proton decays via the Callan-Rubakov process. In this scenario, protons, which initially decay into pions, will ultimately produce nu_e, nu_mu and nu_mu_bar. After going through neutrino oscillation, all neutrino species appear when they arrive at the Earth, and can be detected by a 50000 ton water Cherenkov detector,...

The NEMO-3 experiment located in the Modane Underground Laboratory is searching for neutrinoless double beta decay. The experiment has been taking data since 2003 with seven isotopes. The main isotopes are 7kg of 100Mo and 1kg of 82Se. New results using 150Nd, an isotope of special interest due to its potential use in future experiments, as well as 96Zr and 116Cd will also be presented. No...

In this poster, we present a search for disappearance of active neutrinos over a baseline of 735 km using the NuMI neutrino beam and the MINOS detectors.

MINOS utilizes the most powerful neutrino beam currently in operation measured in two locations: a Near detector at Fermilab, 1~km downstream of beam...

The diffuse supernova relic neutrino signal is of great interest due to
its correlation to cosmological parameters such as star formation rates.
This signal has never been seen. Currently inverse beta decay of
anti-neutrinos in the Super-Kamiokande (SK) detector provides the world's
best upper flux limit of 1.2 nu_e_bar events cm^2 s^-1, E_nu_bar > 19.3

Recent helioseismology results have pointed to the possible detection of high-frequency (periods of minutes to days) gravity-mode oscillation signals in the Sun. Periodic fluctuations in density, pressure and temperature (as would be caused by g-modes at the solar core) could potentially modulate the outgoing flux of solar neutrinos, through the close relationship between temperature and...

In direct dark-matter search experiments, neutrinos coherently scattering off nuclei can produce similar events as Weakly Interacting Massive Particles (WIMPs). Calculations show, that in such experiments, for solar neutrinos a count rate of a few events per ton of target mass and year of exposure are expected. This count rate strongly depends on the nuclear recoil-energy thresholds achieved...

The solution to the problem of the flatness of the SuperKamiokande energy spectrum as observed by the data and which the LMA scenario fails to explain is investigated within the context of neutrino non standard interactions.

Using the formalism by Kimura, Takamura and Yokomakura, the analytic oscillation probability is derived in the presence of new physics in propagation for high energy. While the components \epsilon_{ee}, \epsilon_{e\tau}, \epsilon_{\tau\tau} are allowed to remain relatively large (as was shown by Friedland & Lunardini), it turns out that \epsilon_{e\mu} and \epsilon_{\mu\tau} have conflict...

We discuss a supersymmetric extension of the radiative seesaw model for neutrino masses. The model can induce the tri-bimaximal neutrino mixing and have two dark matter candidates.

The latter one is metastable and its longevity is guaranteed by a...
