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.
Journal ArticleDOI
Precision measurement of neutrino oscillation parameters with KamLAND
TL;DR: The KamLAND experiment has determined a precise value for the neutrino oscillation parameter Deltam21(2) and stringent constraints on theta12 as mentioned in this paper, and the exposure to nuclear reactor antineutrinos is increased almost fourfold over previous results to 2.44 x 10(32) proton yr due to longer livetime and an enlarged fiducial volume.
Journal ArticleDOI
Limit on neutrinoless ββ decay of Xe136 from the first phase of KamLAND-Zen and comparison with the positive claim in Ge76

TL;DR: The combined results from KamLAND-Zen and EXO-200 give T(1/2)(0ν)>3.4×10(25) yr at 90% C.L., which corresponds to a Majorana neutrino mass limit of <(120-250) meV based on a representative range of available matrix element calculations.

TL;DR: Although the present data have limited statistical power, they nevertheless provide by direct means an upper limit for the radiogenic power of U and Th in the Earth, a quantity that is currently poorly constrained.
