The COHERENT collaboration aims to observe coherent elastic neutrino nuclear scattering
(CEvNS) using several detector options including Ge, Ar, NaI and CsI[Na]. The latter has
completed the first year of operation at the Spallation Neutron Source located at the Oak Ridge National Laboratory. The description and status of the CsI[Na] detector will be presented.

The transition and survival probabilities for the different light neutrinos are calculated with account of contributions of heavy neutrinos. The graphical dependences are obtained for the disappearance probability of muon neutrino/antineutrino and appearance probability of electron neutrino/antineutrino in the muon neutrino/antineutrino flux as functions of distance and other model parameters...

The talk covers two topics: neutrinoless double-beta decay search using $^{136}$Xe at KamLAND-Zen, and direct Dark Matter search using ultra-radio-pure NaI(Tl) detectors at KamLAND underground facilities. The KamLAND-Zen is currently the largest neutrinoless double beta decay experiment which holds world's best limit on $T_{1/2}^{0\nu} > 1.07 \times 10^{26}$ yr at 90% C.L.. This limit...

The investigation of neutrinoless double beta decay (0vββ), violating lepton number, is the only practically viable experimental approach to discriminate between Majorana and Dirac character of neutrinos. The observation of neutrinoless double beta decay would also provide a value of its effective mass [m ββ], and possibly in the future, open the window to study CP violation in the lepton...

The GERmanium Detector Array (GERDA) experiment at the INFN Gran Sasso Laboratory, Italy, is searching for the neutrinoless double beta (0νββ) decay of the isotope $^{76}$Ge. High-purity germanium crystals enriched in $^{76}$Ge, simultaneously used as source and detector, are directly deployed into ultra-pure cryogenic liquid argon, which acts both as cooling medium and shield against the...

Setup description and the latest results for EXO-200 experiment are presented. Detector is liquid xenon TPC dedicated to study of 136Xe double beta decay. It contains ~150 kg of xenon and is located in underground low-background laboratory. Careful material selection and cleaning procedures along with complicated analysis resulted in one of the lowest Background Index among low-background...

Non direct observations demonstrate that Earth heat flux could be sufficiently larger than one measured by using of the temperature gradient method. Analysis of heat transfer channels also ensures that heat flux could be higher. At the moment data on 238U and 232Th antineutrino fluxes from KamLAND and Borexino measurements do not contradict the BSE model. Accurate measurement of all...

The Double Chooz experiment (DC) is a reactor neutrino oscillation
experiment running at Chooz nuclear power plant (2 reactors) in France.
In 2011, DC first reported indication of non-zero θ13 mixing angle with
the far detector (FD) located at the maximum of oscillation effects
(i.e. disappearance), thus challenging the CHOOZ non-observation limit.
A robust observation of θ13...
