We report new results from the search for neutrinoless double-beta decay in $^{130}$Te with CUORE detector. This benefits a four-fold increase exposure, lower trigger thresholds and analysis improvements relative to our previous results. observe background of $(1.38\pm0.07)\cdot10^{-2}$ counts$/($keV$\cdot$kg$\cdot$yr$)$ $0\nu\beta\beta$ region interest and, total exposure 372.5 kg$\cdot$yr, we attain median exclusion sensitivity $1.7\cdot10^{25}$ yr. find no evidence set $90\%$ CI Bayesian...
Abstract The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from symmetric theory of fermions proposed by Ettore Majorana in 1937 1 . Given profound consequences such neutrinos, which is a potential explanation for matter–antimatter asymmetry universe via leptogenesis 2 , nature commands intense experimental scrutiny globally; one primary probes neutrinoless double beta (0 νββ ) decay. Here we show results search 0 decay 130...
A bstract The three precision measurements of the cross section σ ( e + − → π γ(γ)) using initial state radiation by KLOE collaboration provide an important input for prediction hadronic contribution to anomalous magnetic moment muon. These are correlated both statistical and systematic uncertainties and, therefore, simultaneous use these requires covariance matrices that fully describe correlations. We present construction them determine a combined measurement γ(γ)). find, from this...
We measured two-neutrino double beta decay of $^{130}\mathrm{Te}$ using an exposure 300.7 kg yr accumulated with the CUORE detector. Using a Bayesian analysis to fit simulated spectra experimental data, it was possible disentangle all major background sources and precisely measure contribution. The half-life is in agreement past measurements strongly reduced uncertainty:...
We searched for the $μ^+μ^-$ decay of a light vector gauge boson, also known as dark photon, in $e^+ e^- \to μ^+ μ^- γ_{\rm ISR}$ process by means Initial State Radiation (ISR) method. used 1.93~fb$^{-1}$ data collected KLOE experiment at DA$Φ$NE $ϕ$-factory. No structures have been observed over irreducible $μ^+ μ^-$ background. A 90\% CL limit on ratio $\varepsilon^2=α^{\prime}/α$ between coupling constant and fine structure $ 3\times 10^{-6}-2\times 10^{-7}$ has set photon mass region 519...

A scintillating bolometer based on a large cubic Li$_{2}$$^{100}$MoO$_4$ crystal (45 mm side) and Ge wafer (scintillation detector) has been operated in the CROSS cryogenic facility at Canfranc underground laboratory Spain. The dual-readout detector is prototype of technology that will be used next-generation $0\nu2\beta$ experiment CUPID. measurements were performed 18 12 mK temperature pulse tube dilution refrigerator. This setup utilizes same as CUORE cryostat host CUPID so represents an...

An array of twelve 0.28 kg lithium molybdate (LMO) low-temperature bolometers equipped with 16 bolometric Ge light detectors, aiming at optimization detector structure for CROSS and CUPID double-beta decay experiments, was constructed tested in a low-background pulse-tube-based cryostat the Canfranc underground laboratory Spain. Performance scintillating studied depending on size phonon NTD-Ge sensors glued to both LMO absorbers, shape detectors (circular vs. square, from two suppliers),...
A bstract Using 1.63 fb −1 of integrated luminosity collected by the KLOE experiment about 7 × 10 4 K S → π ± e ∓ ν decays have been reconstructed. The measured value charge asymmetry for this decay is = (−4.9 5.7 stat 2.6 syst ) −3 , which almost twice more precise than previous result. combination these two measurements gives (−3.8 5.0 and, together with L semileptonic decay, provides significant tests CPT symmetry. obtained results are in agreement invariance.

The Cryogenic Underground Observatory for Rare Events (CUORE) at Laboratori Nazionali del Gran Sasso of INFN in Italy is an experiment searching neutrinoless double beta (0νββ) decay. Its main goal to investigate this decay ^{130}Te, but its ton-scale mass and low background make CUORE sensitive other rare processes as well. In Letter, we present our first results on the search 0νββ ^{128}Te, Te isotope with second highest natural isotopic abundance. We find no evidence decay, using a...
