Abstract

We report on a search for neutrinoless double-beta decay of Xe136 with EXO-200. No signal is observed for an exposure of 32.5 kg yr, with a background of 1.5×103kg1yr1keV1 in the ±1σ region of interest. This sets a lower limit on the half-life of the neutrinoless double-beta decay T1/20νββ(Xe136)>1.6×1025yr (90% C.L.), corresponding to effective Majorana masses of less than 140–380 meV, depending on the matrix element calculation.
