TL;DR: An improved search for neutrinoless double-beta (0νββ) decay of ^{136}Xe in the KamLAND-Zen experiment is presented and a significant reduction of the xenon-loaded liquid scintillator contaminant identified in previous searches is achieved.

TL;DR: This corrects the article DOI: 10.1103/PhysRevLett.117.082503 to reflect that the paper was originally published in Physical Review Letters, not RevLett, rather than Science.

TL;DR: The KamLAND experiment has determined a precise value for the neutrino oscillation parameter Deltam21(2) and stringent constraints on theta12 and analysis of the reactor spectrum above the inverse beta decay energy threshold, and including geoneutrinos, gives a best fit.

TL;DR: An improved formalism for the two-neutrino ββ rate allows us to measure the ratio of the leading and subleading 2νββ nuclear matrix elements (NMEs) and reveals that predicted ξ_{31}^{2ν} values are sensitive to the quenching of NMEs and the competing contributions from low- and high-energy states in the intermediate nucleus.
