Search for the Majorana Nature of Neutrinos in the Inverted Mass Ordering Region with KamLAND-Zen

S. Abe et al.

Summary: The KamLAND-Zen experiment has placed strict constraints on the half-life of neutrinoless double-beta (0vfifi) decay in 136Xe, using a xenon-loaded liquid scintillator. By upgrading the detector and increasing the amount of xenon, the experiment has achieved an exposure of 970 kg yr of 136Xe. The new data provides valuable insights into backgrounds and requires the use of innovative background rejection techniques. The experiment has set a lower limit for the 0vfifi decay half-life of T0v 1/2 > 2.3 x 1026 yr at 90% C.L., corresponding to upper limits on the effective Majorana neutrino mass of 36-156 meV using commonly adopted nuclear matrix element calculations.

Final Result of the MAJORANA DEMONSTRATOR?s Search for Neutrinoless Double-? Decay in 76Ge

I. J. Arnquist et al.

Summary: The MAJORANA DEMONSTRATOR conducted a search for neutrinoless double-beta decay (0 nu beta beta) in 76Ge using modular arrays of high-purity Ge detectors operated in vacuum cryostats within a low-background shield. The arrays consisted of up to 40.4 kg of detectors, with 27.2 kg enriched to approximately 88% in 76Ge. Through these measurements, the DEMONSTRATOR achieved an accumulated active exposure of 64.5 kg yr. By achieving a world-leading energy resolution of 2.52 keV FWHM at the 2039 keV Q beta beta (0.12%), we established a half-life limit for 0 nu beta beta in 76Ge at T1/2 > 8.3 x 1025 yr (90% C.L.). This result provides upper limits on m beta beta ranging from (113-269) meV (90% C.L.), depending on the choice of nuclear matrix elements.

Toward the discovery of matter creation with neutrinoless ββ decay

Matteo Agostini et al.

Summary: The potential discovery of neutrinoless ββ decay has significant implications, as it can confirm theories about the existence of more matter than antimatter in the universe and the unification of forces at high energy scales. It also supports the idea that neutrinos and antineutrinos can transform into each other. Currently, the field is at a turning point with new experiments being prepared to cover a wider range of parameters, and advancements in nuclear theory and particle theory are being made.

New measurement of double-β decays of 100Mo to excited states of 100Ru with the CUPID-Mo experiment

C. Augier et al.

Summary: The CUPID-Mo experiment was conducted in Modane, France, to demonstrate the CUPID technology. By studying the LMO calorimeters, it was found that Mo-100 undergoes two-neutrino and neutrinoless double-beta decays to the excited states of Ru-100. The measured half-life for the two-neutrino decay to the 0(1)(+) state was (7.5 +/- 1 0.8 (stat.)(-0.3)(+0.4)) x 10(20) years, and new limits were set for other decay modes.

Machine Learning Techniques for Pile-Up Rejection in Cryogenic Calorimeters

G. Fantini et al.

Summary: CUORE Upgrade with Particle IDentification (CUPID) is a planned large-scale experiment that aims to explore the inverted hierarchy of neutrino masses and search for neutrinoless double beta decay of Mo-100 by studying the heat and light signals of a Li2MoO4 (LMO) cryogenic calorimeter array. Pile-up events from standard double beta decay of the candidate isotope are considered as relevant background, and the experiment involves injecting Joule heater pulses to generate pile-up heat events in a small array of LMO crystals operated underground. The performance of supervised learning classifiers on the data and the achieved pile-up rejection efficiency are presented.

Investigation of the Lorentz invariance violation in two-neutrino double-beta decay

S. A. Ghinescu et al.

Summary: We conducted a comprehensive investigation on the Lorentz invariance violation (LIV) effects in two-neutrino double-beta decay, providing formulas for LIV deviations, energy electron spectra, and angular correlations. We confirmed the shifting of electron spectra due to LIV and analyzed other LIV signatures. Comparing electron and angular correlation spectra, we obtained information on the strength and observability of LIV effects. We also presented an alternative method for constraining LIV coefficient and estimated the required statistics for current double-beta decay experiments.
