3) Neutrino physics
Utilizing the powerful reactors as anti-neutrino sources, and eight functionally identical underground detectors, the Daya Bay experiment has studied a wide range of topic of interest in neutrino physics. In this talk, I will report the latest measurement of oscillation parameters, and search for a light sterile neutrino, among others. A recent measurement of evolution of the reactor...

3) Neutrino physics
PROSPECT is a reactor antineutrino experiment whose primary goals are to probe short-baseline oscillations and perform a precise measurement of the U-235 reactor antineutrino spectrum. These goals demand close proximity to a compact research reactor core, posing detector design challenges such as tight space constraints, limited overburden and reactor-correlated backgrounds. Therefore,...

3) Neutrino physics
An observation of neutrinoless double beta decay would allow to shed light onto the particle nature of neutrinos. GERDA (GERmanium Detector Array) aims to discover this process in a background-free search using 76Ge. Bare isotopically enriched high purity germanium detectors are operated in liquid argon. GERDA is located at the Laboratori Nazionali del Gran Sasso (LNGS) of INFN in Italy and...

3) Neutrino physics
The OPERA experiment reached its main goal by proving the appearance of ντ in the CNGS νμ beam. A total sample of 5 candidates fulfilling the analysis defined in the proposal was detected with a S/B ratio of about ten allowing to reject the null hypothesis at 5.1 σ. The search has been extended to ντ-like interactions failing the kinematical analysis defined in the experiment proposal to...

3) Neutrino physics
The NA62 experiment at CERN collected a large sample of charged kaon decays in flight with a minimum bias trigger in 2007. Upper limits on the rate of the charged kaon decay into a muon and a heavy neutral lepton (HNL) obtained from this data are reported for a range of HNL masses.

3) Neutrino physics
The NOvA experiment is a long-baseline accelerator-based neutrino oscillation experiment. It uses the upgraded NuMI beam from Fermilab to measure electron-neutrino appearance and muon-neutrino disappearance between the Near Detector, located at Fermilab, and the Far Detector, located at Ash River, Minnesota. The NuMI beam has recently reached and surpassed the 700kW power benchmark. NOvA's...

3) Neutrino physics
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment reaching the 1-ton scale. The detector consists of an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers. The construction of the experiment and, in particular, the installation of all towers in the cryostat was completed in August 2016: the experiment is now in...

3) Neutrino physics
Measurements of reactor antineutrino play an important role in the efforts at the frontier of the modern physics. The DANSS collaboration presents preliminary results of a one year run with a cubic meter solid state detector placed below 3.1 GW industrial light water reactor. The experiment is sensitive to sterile neutrino in the most interesting region of mixing parameter space. 2500...

3) Neutrino physics
Hyper-Kamiokande is a next generation water Cherekov detector consisting of 2 tanks, each with 187 kton fiducial mass, to be built in a staged approach. Hyper-Kamiokande will detect neutrinos produced by the upgraded J-PARC accelerator complex, as well as atmospheric neutrinos. It will enable us to search for CP violation in the lepton sector with an order of magnitude more data than current...

3) Neutrino physics
The goal of the NEXT (Neutrino Experiment with a Xenon TPC) collaboration is the sensitive search of the neutrino-less double beta decay (ββ0ν) of 136Xe at the Laboratorio Subterraneo de Canfranc (LSC). The observation of such a lepton-number-violation process would prove the Majorana nature of neutrinos, providing also handles for an eventual measurement of the neutrino absolute mass. After a...

3) Neutrino physics
T2K is a long-baseline neutrino oscillation experiment taking data since 2010. A neutrino beam is produced at the J-PARC accelerator in Japan and is sampled at a Near Detector complex 280 m from the neutrino production point and at the far detector, Super-Kamiokande. Beams predominantly composed of muon neutrinos or muon anti-neutrinos have been produced by changing the currents in the...

3) Neutrino physics
Neutrino-less double beta decay is one of the hottest topics in the particle physics, since it could probe long-searched neutrino-mass and its hierarchy, also could confirm that neutrino is Majorana particle. The decay is extremely rare, thus an experiment must have ultimately low background environment. 48Ca has the largest Q value (4.3 MeV) among double beta decay nuclei, which is even much...

3) Neutrino physics
The Borexino experiment, located at the Gran Sasso Laboratory in Italy, is operational since 2007. The unprecedented ultra-low background of the inner scintillating core has allowed to measure the fluxes of different components of the solar neutrino spectrum for the first time, thus probing both solar neutrino oscillations and the Standard Solar Model. We present the newest results on solar...

3) Neutrino physics
In the recent years, major milestones in neutrino physics were accomplished at nuclear reactors: the smallest neutrino mixing angle θ13 was determined with high precision and the emitted antineutrino spectrum was measured at unprecedented resolution. However, two anomalies, the first one related to the absolute flux and the second one to the spectral shape, have yet to be solved. The flux...
