CUPID-0 is the first large mass neutrinoless double beta decay (0νDBD) experiment based on cryogenic calorimeters with dual read-out of light and heat for background rejection. The detector, consisting of 26 ZnSe crystals, 2 natural and 24 enriched at 95% in Se82, coupled with bolometric light detectors, has been constructed respecting very strict protocols and procedures, from the material...

The PandaX-III experiment uses high pressure Time Projection Chambers (TPCs) to search for neutrinoless double-beta decay of Xe-136 with high energy resolution and sensitivity at the China Jin-Ping underground Laboratory II (CJPL-II). Fine-pitch Microbulk Micromegas will be used for charge amplification and readout in order to reconstruct both the energy and track of the... -

The direct search for dark matter (DM) at the sub-GeV/c² mass scale gained special interest during the last years, mainly motivated by various theoretical models. To search for individual DM-electron interactions in Si-semiconductor devices a readout noise level of less than 1e- RMS is required.
One possible technique which promise a sub-electron noise level is the *Depleted P-channel Field...

The future Neutrinoless Double Beta Decay (0νDBD) experiments will require a particle detector easily scalable in mass and able to reach good energy resolution (around 2% or better) in the region of interest for the study of these rare decays, at about 3 MeV.

Status of the NEXT project
Go to contribution page
The NEXT program is developing the technology of high-pressure Xe gas TPCs with electroluminescent amplification (HPXe-EL) for neutrinoless double beta decay searches. The first phase of the program included the operation of two small prototypes, NEXT-DEMO and NEXT-DBDM, which demonstrated the robustness of the technology, its excellent energy resolution and its... -

The use of high-purity germanium (HPGe) detectors enriched in the isotope $^{76}$Ge is one of the most promising techniques to search for neutrinoless double-beta decay, a process forbidden in the Standard Model of particle physics. A discovery of this lepton number violating process might answer the question of why the universe consists of matter (but not antimatter) and consequently, why...

The GERDA experiment searches for the lepton number violating neutrinoless double-beta decay of 76Ge operating bare, enriched Ge diodes in liquid argon. The BEGe detectors feature an excellent background discrimination from the analysis of the time profile of the detector signals, while the instrumentation of the cryogenic liquid volume surrounding the germanium detectors acts as an active...

The detection of coherent-neutrino nucleus scattering (CEνNS) opens the door for new physics within and beyond the Standard Model of Particle Physics. NU-CLEUS is a novel neutrino experiment at a nuclear power reactor which allows for precision measurements with a novel cryogenic gram-scale detector design based on CRESST technology. A recent prototype detector has achieved an ultra-low energy...

The observation of a neutrino-less double-beta (0$\nu\beta\beta$) decay
Go to contribution page
would be evidence of neutrino's Majorana nature, and it might be a clue
to explain the baryon asymmetry and the extremely light neutrino masses.
The half-life of 0$\nu\beta\beta$ decay is more than 10$^{26}$ year in
case of $^{136}$Xe, thus it is important to make radiopure detector to
find the very rare... -

A new mechanism of proportional electroluminescence (EL) in two-phase Ar has been revealed, namely that of neutral bremsstrahlung (NBrS), that quantitatively describes the photon emission below the Ar excitation threshold and non-VUV component above the threshold. This paves the way for direct readout of electroluminescence (S2) signals in two-phase TPCs, using PMT and SiPM matrices, in...

Nature and properties of the Dark Matter (DM) in the Universe are among the most fundamental questions of the modern particle physics and astrophysics. So far, the only experiment that claimed detection of a signal from the DM is the DAMA/LIBRA NaI(Tl) experiment located at the Gran Sasso underground laboratory in Italy. Until the recent time, the main obstacle in repeating the DAMA/LIBRA...

The long baseline neutrino experiment T2K has launched the upgrade project of its near detector ND280, crucial to reduce the systematic uncertainty in the prediction of number of events at the far detector to less than 4%. An essential component of this upgrade is a highly segmented scintillator detector, acting as a fully active target for the neutrino interactions.

Superconducting detectors (SCDs) are widely used in astroparticle physics experiments such as dark matter search and cosmic microwave background experiments. Kinetic Inductance Detector (KID) is one of the promising SDCs since KID has several technical advantages: very low fundamental noise, easy fabrication, and high scalability with frequency domain multiplexing. KID consists of microwave...

Ones of the candidates for the Dark Matters are weakly interacting massive particles (WIMPs), and we expect that the Earth should experience a “wind” (named 'WIMP wind') against the direction of the rotation, where is direction to Cygnus.

The SuperNEMO experiment will study decays of 82Se in order to look for neutrinoless double beta decays (0νββ), interactions that, if observed, would prove the Majorana nature of neutrinos. SuperNEMO inherits the tracking-calorimetry technology of NEMO-3, which allows for a clear determination of event kinematics, while aiming for an improved background suppression and 0νββ sensitivity. A...
