TL;DR: In this article, a study of neutrino oscillation based on a 766 ton/year exposure of KamLAND to reactor antineutrinos is presented, where the observed energy spectrum disagrees with the expected spectral shape.

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.
