The first results of neutrino oscillation analysis from the Double Chooz experiment is presented. Double Chooz aims to measure theta_13 precisely using two detectors with different baselines at approximately 400 m for near and 1 km for far detectors. Systematic uncertainties will be strongly suppressed by the two detectors. Double Chooz started physics data taking by the far detector since...

Borexino is a large-volume liquid scintillator detector installed in
the underground halls of the Laboratori Nazionali del Gran Sasso in
Italy. After several years of construction, data taking started in May
2007. The Borexino phase I ended after about three years of data
taking. Borexino provided the first real time measurement of the 7Be solar neutrino interaction rate and confirmed the...

Double beta decay can be the dominant decay mode of some even-even nuclei for which the single beta decay is energetically forbidden or highly spin suppressed. This is a Standard Model second order weak process that produces, among other things, two neutrinos (2νββ). Should neutrinos be Majorana in nature, double beta decay could proceed without the emission neutrinos (0νββ). The observation...

The experimental rate of neutrinoless double beta decay can be saturated by the exchange of virtual sterile neutrinos, that mix with the ordinary neutrinos and are heavier than 200 MeV. Interestingly, this hypothesis is subject only to marginal experimental constraints, because of the new nuclear matrix elements. This possibility has been analyzed in the context of the Type I seesaw model,...
