This talk is focused on a general description of the OPERA experiment, which is designed to observe directly the appearance of nu-tau produced by neutrino oscillations in an almost pure nu_mu beam.
The neutrino beam is produced at CERN and detected 730 km away in an underground hall of the National Laboratory of Gran Sasso.
OPERA detector is a hybrid structure, containing nuclear emulsion...

The present talk highlights the data analysis status of the OPERA experiment. The experiment exploited the CNGS beam from CERN to Gran Sasso, at the average L/E ratio of 43 km/GeV, optimized to search for ν_μ→ν_τ oscillation in appearance mode, and also allowing to perform a ν_e appearance search. Profiting of the sub-micrometer spatial resolution of nuclear emulsions, employed in the OPERA...

KATRIN project has a goal to set electron antineutrino mass upper limit at 0.2 eV level. Installation construction at Karlsruhe Institute of Technology (KIT) proceeds to it final stage. Inner electrodes are installed inside the main spectrometer and first background tests are launched. Windowless gaseous tritium source (WGTS) temperature stabilization was proven to provide 20 mK temperature...

The study of neutrinoless double beta decay ($0\nu\beta\beta$) is a powerful approach to investigate fundamental properties of neutrinos. The observation of $0\nu\beta\beta$ would demonstrate lepton number violation in nature and prove that neutrinos have a Majorana component. It will also give an access to the neutrino mass hierarchy and to the information on the absolute values of the...
