Neutrinos, the puzzling elementary particles, with neutral electric charge and tiny mass, interact with matter very rarely, and are among the most abundant particles in the Universe. The LIP neutrino physics team was created in 2005 to participate in the Sudbury Neutrino Observatory (SNO) and now participates in both the SNO+ and DUNE experiments. SNO+ is taking data right now in SNOLAB, an ultra-clean underground laboratory in Canada, and carrying out measurements of neutrinos from the Sun, nuclear reactors and other rare processes. Once we load the detector with almost 4 tonnes of Tellurium, the main goal is the observation of neutrinoless double beta decay to probe the possible Majorana character of neutrinos and measure its absolute mass.
DUNE aims at measuring differences in the oscillations of muon neutrinos and muon anti-neutrinos, that would indicate violation of the CP symmetry in the lepton sector. It is a new major worldwide project, that will still take years to build, but there is much to do to design the experiment and test prototypes.
