The T2K experiment is a long baseline neutrino experiment. The baseline is the 295 km from the J-PARC accelerator in Tokai to Super-Kamiokande. We will present our results using data taken from Jan. 2010 to Jul. 2012. This data corresponds to about 4% of our ultimate statistics. I will show the results of the muon neutrino disappearance measurement and the electron neutrino appearance...

The OPERA experiment has been designed to perform the first detection of neutrino oscillations in the Nu_mu-->Nu_tau channel, in direct appearance mode through the event by event detection of the tau lepton produced in Nu_tau Charged Current interactions. OPERA is a hybrid detector, made of emulsion/lead target elements and of electronic detectors, placed in the CNGS muon neutrino beam from...

The Daya Bay experiment is designed to measure the smallest neutrino mixing angle θ13 precisely using reactor anti-neutrinos. It is located at the Daya Bay Nuclear Power Complex in southern China, and consists of eight antineutrino detectors deployed in three underground experimental halls at different baselines from three clusters of nuclear reactors. Low-energy electron anti-neutrinos...

Double Chooz is a reactor antineutrino experiment built to measure a mixing angle theta-13. The experiment uses two detectors at different baselines (400 m and 1 km) to precisely measure the disappearance of electron flavor anti-neutrino from the Chooz reactor cores in Ardenne, France. Our inverse beta decay (IBD) signal is a two-fold coincidence of a prompt positron followed by a delayed...

The KamLAND-Zen experiment is a new application of the KamLAND detector running in parallel with the ongoing antineutrino program at KamLAND. The experiment searches for neutrinoless double beta decay of $^{136}$Xe using a target of Xe-loaded liquid scintillator placed at the center of the KamLAND detector. KamLAND-Zen recently completed its first phase of running, corresponding to the...

The GERmanium Detector Array (GERDA) experiment searches for the
neutrinoless double beta decay of Ge-76. It is a lepton-violating process which can shed light on the Dirac vs. Majorana nature of the neutrino.
The experiment is located at the Gran Sasso Undergound Laboratory (LNGS) of INFN, Italy.
High-purity Germanium detectors enriched in the isotope 76 are operated bare in liquid argon,...

The Borexino experiment was the first to directly investigate the sub-MeV region of the solar spectrum. Its search for answers
to some fundamental questions in the field of neutrino oscillations was accomplished with a precision measurement of the $^{7}$Be line at 5\%; Borexino detected 46.0$\pm1.5_{\rm stat}$$^{+1.6}_{-1.5\,\rm syst}$ solar neutrino events/day/(100 tons) during Phase I of...

We study the possibility to perform neutrino oscillation tomography and to determine the neutrino mass hierarchy in kilometer-scale ice Cerenkov detectors by means of the theta13-driven matter effects which occur during the propagation of atmospheric neutrinos deep through the Earth. We consider the ongoing IceCube/DeepCore neutrino observatory and future planned extensions, such as the PINGU...

The constraints from recent observations of the Cosmic Microwave Background (CMB) on neutrinos are considered. Results are discussed both with CMB information only as well as in conjunction with other tracers of large scale structure.

Recent cosmological data favor additional relativistic degrees of freedom beyond the three active neutrinos and photons. Light sterile neutrinos are prime candidates for such additional radiation. I will discuss the evolution of light sterile neutrinos in the early universe, their role as dark-radiation candidates and present cosmological constraints.

EXO-200 is a double beta decay experiment, that uses ~200kg of liquid Xe, enriched to ~80% Xe-136, in a cylindrical time projection chamber. EXO-200 is located at the WIPP facility near Carlsbad, New Mexico. Double beta decay is a second order
weak process in the Standard Model (A,Z)X $->$ (A,Z+2)Y +2e + 2nu
(2 neutrino double beta decay) and has been measured with 11 even-even isotopes....

CUORE-0 is a neutrinoless double beta decay experiment consisting of an array of 52 TeO2 bolometers for a total detector mass of about 40 kg. Its goal is to investigate the Majorana electron neutrino mass in the range expected for the Quasi Degenerate scenario, while providing a test of proof for the future CUORE experiment. This will be a 1-ton array designed to reach a sensitivity into the...
