EXO-200 is one of the most sensitive searches for neutrinoless double beta decay in the world. The experiment uses 175 kg of enriched liquid xenon in an ultralow background time projection chamber installed at the Waste Isolation Pilot Plant, a salt mine with a 1600 m water equivalent overburden. This detector has demonstrated excellent energy resolution and background rejection capabilities....

The nEXO Collaboration is designing a very large detector for neutrino-less double beta decay of Xe-136. The nEXO detector is rooted in the the currently-running EXO-200 program, which has reached a sensitivity for the half life of the decay of 1.9 x 10^25 years with and exposure of 99.8 kg-yr. The baseline nEXO design uses 5 tonnes of liquid xenon, enriched in the mass 136 isotope, in a...

CANDLES is the project to search for neutrino-less double beta
decay (0$\nu\beta\beta$) of $^{48}$Ca.
0$\nu\beta\beta$ is acquiring great interest
after the confirmation of neutrino oscillation
which demonstrated nonzero neutrino mass.
Measurement of 0$\nu\beta\beta$ provides a test for the Majorana nature of neutrinos
and gives an absolute scale of the effective neutrino mass.

An observation of neutrinoless double-beta decay ($0\nu\beta\beta$) identifies the neutrino as a Majorana particle and constrains the absolute mass scale of neutrinos. The {\sc Majorana} collaboration is constructing an array of high purity germanium detectors that are isotopically enriched in $^{76}$Ge that will serve as both a source and detector of $0\nu\beta\beta$. In the presence of...

NEXT (an acronym for Neutrinoless Experiment with a Xenon TPC) will search for the neutrinoless double beta decay of 136Xe using a radiopure high-pressure xenon gas TPC filled with 100 kg of Xe enriched in its 136Xe isotope. A measurement of this hypothetical process would provide direct information on neutrino masses at the same time that would lead to a better understanding of many aspects...

Project 8 aims to determine the neutrino mass from the beta-decay of tritium (Q = 18.6 keV).
Since the cyclotron frequency of a charged particle traveling in a homogeneous magnetic field is inversely proportional to its total energy, a measurement of this frequency provides accurate knowledge of the particle's total energy. This allows the reconstruction of the electron energy spectrum from...

Neutrino properties, and in particular the open question regarding the scale of neutrino rest masses, bear fundamental relevance to many current research topics in cosmology, theoretical particle physics, and astroparticle physics.
Due to the smallness of neutrino masses, the determination of their absolute scale is a challenging experimental task. Precision measurements of the kinematics of...

Several observed anomalies in the neutrino sector could be explained by a fourth (sterile) neutrino with a squared mass difference in the order of 1eV² to the other three standard neutrinos. This hypothesis can be tested with an artificial MCi neutrino (Cr-51) or a kCi antineutrino (Ce-144/Pr-144) source deployed near or inside a large low background detector like Borexino. The SOX project...

The question of the existence of sterile states for neutrinos is addressed since many years. If they exist such states would not be directly detected but could mix with the three ordinary states and would be “seen” as new oscillations in the propagation of the neutrinos. Recently this question arose by the observation of a small deficit of anti-neutrinos with respect to predictions by previous...

IsoDAR is an innovative experimental concept to use a high power, low energy cyclotron to produce a source of electron antineutrinos. Such an intense source, when combined with a liquid scintillator based detector, can provide a direct probe of the reactor antineutrino anomaly and, in general, a definitive test of the sterile neutrino. Further, IsoDAR can distinguish between one and two...

At the quantum level, an interaction of a neutrino with a graviton may

eigenstate. I will present that such an essentially quantum gravity effect
may have strong consequences for neutrino oscillation phenomena in

relativistic neutrinos off...

With the advent of low-threshold detectors that look for neutrino scattering at sub-keV energy deposition, the sensitivity to possible neutrino electromagnetic moments can be further increased. As such low energies start to overlap with atomic scales, it is necessary to take atomic binding effects into account so that detector responses can be understood more reliably. In this talk, we present...

Cosmology and particle physics come across a tight connection in the attempt to reproduce quantitatively
the results of experimental findings. Indeed, the dark matter relic abundance and the amount of
baryon asymmetry in the universe are accurately determined by the recent analysis of the cosmic microwave background. The Standard Model can not account for none of these evidences.
