We present results of a study neutrino oscillation based on 766 ton-year exposure KamLAND to reactor anti-neutrinos. observe 258 \nuebar\ candidate events with energies above 3.4 MeV compared 365.2 expected in the absence oscillation. Accounting for 17.8 background events, statistical significance \nuebar disappearance is 99.998%. The observed energy spectrum disagrees spectral shape at 99.6% and prefers distortion from effects. A two-neutrino analysis data gives \DeltaMSq =...
The CUPID-Mo experiment at the Laboratoire Souterrain de Modane (France) is a demonstrator for CUPID, next-generation ton-scale bolometric $0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$ experiment. It consists of 4.2 kg array 20 enriched ${\mathrm{Li}}_{2}$$^{100}\mathrm{Mo}{\mathrm{O}}_{4}$ scintillating bolometers to search lepton-number-violating process decay in $^{100}\mathrm{Mo}$. With more than one year operation ($^{100}\mathrm{Mo}$ exposure $1.17\text{ }\text{...

Neutrinoless double beta decay (0νββ) is a yet unobserved nuclear process that would demonstrate Lepton number violation, clear evidence of beyond standard model physics. The two neutrino (2νββ) allowed by the and has been measured in numerous experiments. In this Letter, we report measurement 2νββ half-life Mo100 to ground state Ru100 [7.07±0.02(stat)±0.11(syst)]×1018 yr CUPID-Mo experiment. With relative precision ±1.6% most precise date rate Mo100. addition, constrain higher-order...
The CUPID-Mo experiment, located at the Laboratoire Souterrain de Modane (France), was a demonstrator experiment for CUPID. It consisted of an array 20Li2Mo100O4 (LMO) calorimeters, each equipped with Ge light detector particle identification. In this work, we present result search two-neutrino and neutrinoless double-β decays Mo100 to first 0+ 2+ excited states Ru100 using full exposure (2.71kgyr LMO). We measure half-life 2νββ decay 01+ state as...
The Kamioka Liquid scintillator Anti-Neutrino Detector is used in a search for single neutron or two-neutron intranuclear disappearance that would produce holes the s-shell energy level of 12C nuclei. Such could be created as result nucleon decay into invisible modes (inv), e.g., n→3ν nn→2ν. deexcitation corresponding daughter nucleus results sequence space and time-correlated events observable liquid detector. We report on new limits one- disappearance: τ(n→inv)>5.8×1029 years...

The basic principle of operation silicon sensors with resistive read-out is built-in charge sharing. Resistive Silicon Detectors (RSD, also known as AC-LGAD), exploiting the signals seen on electrodes surrounding impact point, achieve excellent space and time resolutions even very large pixels. In this paper, a TCT system using 1064 nm picosecond laser used to characterize RSD produced by Fondazione Bruno Kessler. paper first introduces parametrization errors in determination position...
In the context of direct searches sub-GeV Dark Matter particles with germanium detectors, EDELWEISS collaboration has tested a new technique to tag ionizing events using NbSi transition edge athermal phonon sensors. The emission phonons generated by Neganov-Trofimov-Luke effect associated drift electrons and holes through detectors is used ionization in specific parts detector localized front sensor reject more than factor 5 (at 90% C.L.) background from heat-only that dominates spectrum...
