abstract
We propose the construction of LEGEND-1000, the ton-scale Large Enriched Germanium Experiment for Neutrinoless $\beta \beta$ Decay. This international experiment is designed to answer one of the highest priority questions in fundamental physics. It consists of 1000 kg of Ge detectors enriched to more than 90% in the $^{76}$Ge isotope operated in a liquid argon active shield at a deep underground laboratory. By combining the lowest background levels with the best energy resolution in the field, LEGEND-1000 will perform a quasi-background-free search and can make an unambiguous discovery of neutrinoless double-beta decay with just a handful of counts at the decay $Q$ value. The experiment is designed to probe this decay with a 99.7%-CL discovery sensitivity in the $^{76}$Ge half-life of $1.3\times10^{28}$ years, corresponding to an effective Majorana mass upper limit in the range of 9-21 meV, to cover the inverted-ordering neutrino mass scale with 10 yr of live time.

MR-SCDFT augments standard multireference DFT by using stochastic fields to create reference configurations and a projection-selection step, yielding lower ground-state energies, smaller proton radii, and softer bands than conventional MR-CDFT for 20Ne, 24Mg, and 28Si.
A neutron activation and radiochemical precipitation method achieves a minimum detectable concentration of 2.9·10⁻¹⁶ g/g for 40K in organic liquid scintillators.
Octonionic Cl(6) flavor structure yields φ12 = -2χ for quarks and real lepton amplitudes unless identity-flavor plane mixing occurs.
DESI DR2 data constrain the neutrino mass sum below the inverted hierarchy minimum, yielding Bayes factor K>460 for normal hierarchy in standard cosmology.
Combining 0νββ decay experiment results with ab initio nuclear matrix elements in a Bayesian framework yields stronger global Majorana neutrino mass limits than individual experiments, indicating current searches have not reached the oscillation-allowed regime.
Ab initio IMSRG calculations give smaller short-range 0νββ nuclear matrix elements for 76Ge, 82Se, 130Te and 136Xe than phenomenology, yielding updated sterile-neutrino mixing constraints.
Lattice QCD evaluation of π⁻→π⁺ee matrix elements at physical pion mass with a new around-the-world subtraction technique and RI/SMOM renormalization that reduces uncertainties and cross-checks prior results.
A LangChain-based vision AI agent extracts cylinder diameters from hydrostatic test videos using SAM2 segmentation and reconstructs hoop stress-strain curves and yield strengths that agree with simulations.
