TL;DR: New results from EXO-200 based on a large 136Xe exposure are reported, finding no statistically significant evidence for 0νββ decay and set a half-life limit of 1.1 × 1025 years at the 90 per cent confidence level.

TL;DR: This work sets a lower limit on the half-life of the neutrinoless double-beta decay T(1/2)(0νββ)(136Xe)>1.6×10(25) yr (90% C.L.), corresponding to effective Majorana masses of less than 140-380 meV, depending on the matrix element calculation.

TL;DR: The observed decay rate provides new input to matrix element calculations and to the search for the more interesting neutrinoless double-beta decay, the most sensitive probe for the existence of Majorana particles and the measurement of the neutrino mass scale.

TL;DR: The EXO-200 detector as discussed by the authors was designed to search for double beta decay of 136Xe with a single-phase liquid xenon detector, which uses an active mass of 110 kg of xenon enriched to 80.6% in the isotope 136 in an ultra low background time projection chamber capable of simultaneous detection of ionization and scintillation.
