The OPERA experiment, located in the underground Gran Sasso laboratory is designed to detect mu-neutrino to tau-neutrino oscillations in appearance mode. The detectors, placed on the long-baseline CERN to Gran Sasso neutrino beam (CNGS) 730 km away from the source, consists of an emulsion/lead target complemented by electronic detectors. OPERA has been taking data for five years, from 2008 to...

The Tokai to Kamioka (T2K) experiment is a long baseline neutrino oscillation experiment situated in Japan. A high intensity neutrino beam is produced at the Japan Proton Accelerator Research Complex, in Tokai, Japan. A near detector complex, situated 280 m from the neutrino production target, and the far detector at 295 km, are used to detect the neutrinos from this beam. This talk will...

The large value of $\theta_{13}$ recently discovered at reactor neutrino experiments has opened the door to determine the ordering of their mass eigenstates in the near future. However, since the neutrino mass ordering is a discrete parameter it is not clear whether the median sensitivity of a given experiment would coincide with the usual values reported in the literature. I will present a...

New oscillation results from the Double Chooz experiment will be presented, accounting for the data collected in 467.9 live days. The precision in the measurement of the mixing angle theta13 has been improved by means of a higher signal-to-background ratio and reduced systematic uncertainties in detection, backgrounds and energy scale. This new powerful analysis will boost the results of the...

The Standard Theory of elementary particle physics admits a large flavor symmetry in the absence of Yukawa interactions. This symmetry is assumed to be exact at high energies but hidden in the regime explored so far. The naturalness of this assumption is explored with emphasis on the possible explanation of the difference in the observed mixing patterns in the lepton and quark sectors.

The Borexino experiment located in the Gran Sasso National Laboratory, is an organic liquid scintillator detector concieved for the real time spectroscopy of low energy solar neutrinos. The data taking campaign phase I (2007 - 2010) has allowed the first independent measurements of 7Be and pep solar neutrino fluxes as well as the first measurement of anti-neutrinos from the earth. After a...

Solid evidence for non-zero neutrino masses has been established by oscillation experiments but their absolute scale remains unknown. The neutrino mass can be composed of Dirac and Majorana mass terms. A Majorana mass term would result in total lepton number violation and have fundamental implications for cosmology. The only feasible experimental approach to investigate the Majorana nature of...

An accurate and precise understanding of neutrino-nucleus interactions in the few-GeV energy region is vital for the success of the worldwide neutrino oscillation programme. In this talk, I will show measurements of neutrino cross sections taken at the MINERvA experiment which constrain interaction channels that are relevant for oscillation experiments.

In this talk we will discuss neutrino oscillations involving eV-scale neutrino mass states, in the context of global neutrino oscillation data including short and long-baseline accelerator, reactor, and radioactive source experiments, as well as atmospheric and solar neutrinos. We consider sterile neutrino mass schemes involving one or two mass-squared differences at the eV^2 scale denoted by...

KamLAND-Zen is an experiment of search for neutrinoless double beta decay with KamLAND Detector,
in Kamioka mine, Japan.
We achieved the most stringent limit on neutrinoless double beta decay of Xe-136,
and the purification for background reduction has been processed in the last year and a half.
I report the results and current status from KamLAND-Zen.

The NEMO-3 detector, installed in the Modane underground laboratory, ran between February 2003 and January 2011. The NEMO-3 experiment employed a tracker and calorimeter detector technology to fully reconstruct the topology of the events generated in thin foils of active material. Thanks to its unique design, NEMO-3 studied the details of the Double-β decay in seven isotopes (100Mo, 82Se,...
