The T2K long-baseline experiment is located in Japan and is designed to study oscillations of muon neutrinos. T2K receives a beam of muon neutrinos peaked at 0.6 GeV that are produced at J-PARC accelerator complex by converting a beam of 30-GeV protons hitting a graphite target. Upon travelling 295 km, neutrinos are detected by the Super-Kamiokande water Cherenkov detector. Located at 280 m...

The OPERA experiment at the Gran Sasso underground laboratory is searching
for nu_mu -> nu_tau oscillations in appearance mode in the CNGS neutrino beam.
Four nu_tau candidate events have been found so far, using a sub-sample of data
from the 2008-2012 runs. Given the number of analysed events and the low background,
nu_mu -> nu_tau oscillations are established with a significance of 4.2...

{\sc Gerda} is designed to search for the neutrinoless double beta (0$\nu\beta\beta$) decay, a lepton number violating process. It
employs bare high-purity germanium diodes enriched to 86\,\% in $^{76}$Ge directly immersed in liquid argon. Phase~I operated till May 2013
with a mean background of 1$\cdot10^{-2}$\,cts/(keV$\cdot$kg$\cdot$yr) near the Q-value. GERDA sets a new lower limit...
